NTT DoCoMo is applying to extend its network to the 700MHz spectrum after losing out the coveted 900MHz band to smaller rival Softbank. If successful, the communications giant will have to fork out 150 billion yen ($1.9 billion) to make the necessary infrastructure changes to allow 3.9G devices to work on its network. While it can't be too happy at having to make do with the weaker frequencies, it does expect to pocket nearly $5 billion in profit this year, which ought to cushion the blow.

If you're an iPhone or iPad owner, you might have been disappointed that the Delorme inReach two-way GPS communicator launched with app support only for Android users. That's fine if you're trekking with a Casio G'zOne Commando, but not so hot if you're of the Apple mindset and get stranded canoeing down the Amazon. Thankfully, Delorme just posted an iOS version of its Earthmate app that will let your Cupertino-designed gear send either text messages or SOS beacons through a paired-up inReach unit. As before, the handheld relies on its own GPS positioning and embedded locations in messages to keep friends and rescue crews updated anywhere the device can get an Iridium satellite lock-in. It'll still cost you $250 for the device and $10 per month to stay linked up; even so, there's a real chance you'll be texting your friends from your iPhone in Mali, assuming you haven't had to call a rescue helicopter first.

What's a spankin' new Android phone to do hot off its CTIA 2012 debut? Why, stop by the FCC for an inside-out coming out party. The Kyocera-crafted handset outlined in the docs looks to be the recently unveiled Hydro, as the device's model number -- C5170 -- matches that of the unit we got hands-on with in New Orleans. The filings don't spill much of the middleweight mobile's guts, but we were able to discern radios for CDMA 1900MHz, WiFi b/g/n and Bluetooth, as well as the existence of a 1,500mAh battery. We're still in the dark as to where this waterproofed, ICS-laden phone'll end up, but if our magic 8-ball's any indication, all signs point knowingly to Sprint. Hit up the source below to rifle through the RF tests for yourself.

Android's openness, combined with its popularity, has lead a few of the developer faithful astray -- with malware being a legitimate concern for the mobile operating system. To help combat the issue, Xuxian Jiang, an NC State researcher, has created the Android Malware Genome Project, which was presented at the IEEE Symposium on Security this week. The aim is to collect and analyse all the known malicious software, and share the findings so that more effective and preventative measures to be taken by the community. Jiang claims that the main drawback has been understanding the malware, and getting access to examples, something the project aims to solve. More than 1,200 malware samples have been collected so far, and if you're curious, the dataset is available for download via the source.

Microsoft warned us last month that it would be snipping legacy OS support in Windows Phone Marketplace within a few weeks, and it just made good on that heads-up. As of now, you'll need at least a Windows Phone 7.5 device to shop for, review and update apps, no matter how much you want that fix for Ilo Milo. The company still argues that the cutoff is needed to improve speed and security in the Marketplace as well as lay a foundation for a better Windows Phone future. Given that virtually every handset on the market can get 7.5 today, if it doesn't already ship with 7.5 preloaded, you have every good reason to grab the update through Microsoft's desktop apps and stay in the Marketplace downloading parade.

We love finding out how things work, and arguably one of the most important parts of the smartphones and tablets we thrive on is the accelerometer gauging our device's orientation. Imagine our delight, then, when we see the University of Illinois' Bill Hammack (i.e. The Engineer Guy) giving a visual rundown of how accelerometers work. Although it's certainly the Cliff's Notes version of what's going on in your Android phone or iPhone, the video does a great job of explaining the basic concepts behind three-axis motion sensing and goes on to illustrate how MEMS chips boil the idea down to the silicon form that's needed for our mobile hardware. Hammack contends that it's one of the coolest (and unsung) parts of a smartphone, and we'd definitely agree; you can see why in the clip after the break.

You probably don't give much thought to the towers that blanket us with wireless signals and the technicians that climb up them, almost constantly, to upgrade the equipment. The PBS investigative journalism series, Frontline, does and tonight on your local PBS HD affiliate the findings from their investigation of the numerous fatalities will premier -- check out the embedded preview and then the local listings for specific time and channel. Who's to blame, what can be done to prevent it and more will be covered, as well as discussed via an online chat with the film's producers on Wednesday the 23rd at 1PM ET, with one of our very own moderating the panel. Feel free to leave questions for the producers and then join us tomorrow via the embedded chat after the break.

Comcast took the opportunity at The Cable Show 2012 to introduce some new features for its Xfinity Voice service, dubbed Voice 2Go. The end goal is to bring the perks you enjoy with your smartphone to your landline. It all starts with an app that's available on iOS and Android (in both phone and tablet-friendly formats) that functions similarly to Google Voice. The Xfinity Connect Mobile app allows you to send and receive texts on your mobile device through your home phone number and forward incoming calls to multiple devices, including your cellphone, so you'll never miss a call again. What's more, your Xfinity account can be used to place VoIP calls from any connected device over WiFi, 3G or 4G. For more check out the video after the break.

Nokia has reportedly been dreaming of PureView phones with 4K video; as of today, OmniVision is walking the walk quite a bit earlier. The 16-megapixel resolution of the OV16820 and OV16825 is something we've seen before, but it now has a massive amount of headroom for video. If your smartphone or camcorder has the processing grunt to handle it, either of the sensors can record 4K (3840 x 2160, to be exact) video at a super-smooth 60 fps, or at the camera's full 4608 x 3456 if you're willing to putt along at 30 fps. The pair of backside-illuminated CMOS sensors can burst-shoot still photos at the bigger size, too, and can handle up to 12-bit RAW. Impressive stuff, but if you were hoping for OmniVision to name devices, you'll be disappointed: it's typically quiet about the customer list, and mass production isn't due for either version until the fall. On the upside, it could be next year that we're feeding our 4K projectors with Mr. Blurrycam smartphone videos.

It took nearly a full month, but Nokia has finally been convinced that Skype is indeed incompatible with low-memory Windows Phones. In reaching out to a spokesperson, the company confirmed to us that it has decided to yank the official client from the Marketplace on the Lumia 610. The device -- which utilizes a scant 256MB of RAM -- originally allowed the service to be downloaded despite Skype's claims that 512MB was the minimum amount of memory required for the app to function properly. The internet phone service, as it turns out, was correct: Nokia, stating that the user experience is "workable" but not "up to par with Nokia's and Skype's expectation," has pulled the plug on any future downloads. Users who managed to snag the app before it disappeared can still enjoy (or hate, depending on your experience) it on their Lumia 610, but until Skype is able to lower the memory restrictions, it looks like everyone else is out of luck. Head below for the full translated statement.

It turns out that Motorola didn't want to wait until the Google deal closed -- or, for that matter, an American launch -- to undertake a significant revamp of its phone line. A quiet Chinese event last week is now known to have brought us three RAZR-derived, all-touch phones for the three carriers in the Asian country: the XT885 for China Unicom (pictured at left), XT889 for China Telecom (center) and MT887 for China Mobile (right). Other than the network types and pretty bits, you're mostly looking at the same device, where the highlight is an official dip into Android 4.0 waters that drops the physical navigation in favor of more Nexusish on-screen keys. Don't expect a revolution in performance over last fall's roster given that they still have 1.2GHz dual-core processors, eight-megapixel rear cameras and 4.3-inch, 540 x 960 displays. The trio arrives in China on June 2nd; Motorola is likely more worried about popping champagne than giving out US launch details right now, but earlier leaks give us a strong hunch that the MT887 could hit Verizon as the uncannily similar (if still very unofficial) Droid Fighter before too long.

Welcome to Panasonic's first attempt to crack the increasingly competitive world of Android phones outside of Japan. Its efforts have crystallized into a plastic slab that had a curious appeal when we first handled it at Mobile World Congress a few months ago. We were surprised at how comfortable it felt in the hand and while its spec sheet won't cause any jaws to drop, there's plenty of respectable features -- a 4.3-inch AMOLED display, dual-core processor and a very solid, soft-finish shell that protects that delicate Android hardware against dust and water.

Panasonic's not the only Japanese manufacturer looking to branch out from a contracting domestic market, however, and we have a few concerns with whether the Eluga (£370 / $583) can make a dent in European countries dominated by Apple, Samsung and HTC. Will it bring the same awkward Android skins found on several Japan-only Android phones? Is it really all that waterproof? Dive in after the break to see.

Panasonic Eluga review

Months in the making -- the deal is finally done. Motorola Mobility is officially part of Google. After receiving blessings from Europe, the US and China, the Internet giant has put the finishing touches on its purchase of Moto's mobile division. Though the corporate marriage faced plenty of obstacles, Big G was able to put the manufacturer on its ledger for the price of $40 per share, or about $12.5 billion. As it stands, Motorola Mobility will continue to operate as a separate business entity and as a licensee of Android, but Mountain View is still claiming the purchase will allow it to "supercharge" its mobile ecosystem. The future of the new subsidiary's employees is a different matter, however. Rumors have been swirling for the last week or so that there could be significant layoffs at Moto following the merger, which would further enforce the perception that Google is more interested in the company's patents than in entering the hardware business. Of course, whether or not we'll see layoffs or perhaps a Moto-branded Nexus is still a mystery. For a bit more on Google's victory lap, check out the PR after the break.

Update: Google has also settled on a replacement for Sanjay Jha as CEO of Motorola Mobility, Dennis Woodside. Woodside is a longtime Googler who got his start in sales, building out business in Africa, Eastern Europe and Russia, before becoming President of the Americas sales operation.

Operating on Vodafone's network, Bemilo is a new pay-as-you-go mobile service in the UK that aims to give parents greater control over their child's use of a mobile phone. Among the features, one can specifically set which hours during the day that the phone can be operated (the only exception being calls to mom or dad), which websites can be visited and who the child may contact. Further in the name of safety, all picture and video messages are disallowed from the get-go, and parents can even review their children's text messages -- even after they've been deleted. The Bemilo service runs £2.95 per month, on a month-to-month basis, whereas calls and voicemail access are charged at 10 pence per minute. Text messages run a similar 10p, but data usage will be levied at a steeper 25p per megabyte -- cost-conscious parents may wish to nix this usage entirely. Bemilo's required SIM card may be purchased either directly through the company's website or its partner, Carphone Warehouse. As for the company's mascot, Milo, that's one cute character that your kids will surely resent.

Smartphones have revolutionized how we communicate and the way we create, share and consume content. Yet there's one aspect of using these devices that remains stuck in the last millennium, and that's the calling experience -- yes, apparently some people still make phone calls. Sure, there are plenty of VoIP and video calling apps out there, but few are simple and beautiful.

Enter Sidecar, a free app which aims to reinvent the way we make phone calls by adding messaging as well as real-time video, photo, location and contact sharing to that antiquated calling experience. It achieves this through an intuitive and polished user interface plus a handful of standards such as SIP and XMPP. Phone calls between Sidecar users are free anywhere in the world -- the app even supports free WiFi calling to any number in the US or Canada.

While Sidecar's been available in beta on Android for several weeks, it's launching on iOS today with support for the iPhone and iPod touch. We've been using the app on and off for a few days on several handsets, including a Galaxy Nexus HSPA+ and an iPhone 4S and it works exactly as described. Looking for additional details? Check out the demo video and full PR after the break.

Samsung design VP Chang Dong-hoon has refuted accusations that the Galaxy S III was designed "by lawyers." Responding to the reports that stated the new handset was tweaked to circumvent deliberate trade dress claims made by Cupertino in its lawsuit, he said that the redesign is part of the company's five-year plan rather than a sudden change. He went on to say that the flagship went through hundreds of iterations before the team alighted upon the model that will shortly make its way into sweaty palms all over the world.

As the temperatures heat up, the availability of new network TV programming is falling off as it does every year, and Hulu is taking advantage of the lull to amp up its offerings of original content with ten new shows this summer. The shows include selections like Kevin Smith's Spoilers which is a chat about the summer's films, travel series Up To Speed and playground basketball comedy We Got Next. All ten shows are set to debut throughout the summer on both the free Hulu and paid Hulu Plus services. One thing subscribers don't have to wait for however, is a freshly updated version of the Hulu Plus app for iOS, which features a "re-engineered, optimized video player", new iPad GUI, support for retina display on the iPad and improved handling of AirPlay mirroring and HDMI video out. Version 2.5 can be found on iTunes, while a press release with details on all ten shows and video trailer are embedded after the break.

We've been twiddling our thumbs waiting patiently for the littlest of Sony's new-look smartphone lineup, the Xperia U, to arrive in earnest. It's a bit of a relief then to see the Android 2.3 phone go on sale at Three UK. You'll be getting what we saw back in Barcelona, including Sony's Timescape interface and the trick color light-up strip. We're guessing that most will see the cheap-as-chips price as the real selling point: the Xperia U costs £170 ($269) without a plan, and it's free as in beer on a two-year contract for £23 ($36) per month. O2, Orange and T-Mobile will expand UK carrier choices soon, but if you're looking for a fresh entry point into Android, Three can take care of you today.

Still rockin' Windows Mobile 6.x? Time to check all your apps for updates one last time. Microsoft has issued a final reminder that, beginning today, the Marketplace for 6.x devices will no longer be available. This means you won't be able to browse, buy or download apps from your phone via the service. Everything you already have will, of course, work just fine, but if you needed to reinstall something -- now is the time to do it. Unless it's available direct from third party sites, in which case you'll have a little breathing space. Still, better safe than sorry.

Normally, firewalls at cellular carriers are your best friends, screening out malware before it ever touches your phone. University of Michigan computer science researchers have found that those first lines of defense could be your enemy through a new exploit. As long as a small piece of malware sits on a device, that handset can infer TCP data packet sequence numbers coming from the firewall and hijack a phone's internet traffic with phishing sites, fake messages or other rogue code. The trick works on at least 48 carriers that use firewalls from Check Point, Cisco, Juniper and other networking heavy hitters -- AT&T being one of those providers. Carriers can turn the sequences off, although there are consequences to that as well. The only surefire solution is to either run antivirus apps if you're on a mobile OS like Android or else to run a platform that doesn't allow running unsigned apps at all, like iOS or Windows Phone. Whether or not the exploit is a serious threat is still far from certain, but we'll get a better sense of the risk on May 22nd, when Z. Morley Mao and Zhiyun Qian step up to the podium at an IEEE security symposium and deliver their findings.

Dish Network might not start up its LTE-based 4G network until as late as 2016, but that hasn't stopped MetroPCS and T-Mobile from jointly telling the FCC that the would-be carrier needs to make some concessions for small carriers to rest easy. Both of the complaints have a common proposal that would see Dish give up 20MHz of its 40MHz space in the 2GHz range to prevent the satellite giant from using its abundant airwaves as part of a cash grab: MetroPCS and T-Mobile are worried Dish will just try for a "windfall" and sell the spectrum it doesn't need to AT&T or Verizon. While it's not asking for a sell-off, the Rural Cellular Association is still jittery about concentrations of power and wants the FCC to make Dish hit certain build-out targets, offer roaming at wholesale rates and require FCC approval for any roaming deal that would go to Big Blue or Big Red. The big carriers' advocacy group, the CTIA, is unsurprisingly against build-out demands as "unduly burdensome." FCC officials have been silent by comparison, although the agency has encouraged spreading spectrum around and proposed its own expansion requirements. You'll likely see smartphones with 2GHz frequencies at some point in the future -- it's just a matter of whether Dish or someone else slaps its logo on top.

Have a BMW 3-Series that requires major engine work? Want to convert it to electric and improve performance, ActiveE style? The folks at Electric Motor Werks have you covered. Instead of making purpose-built electric cars, the company -- which showed a converted 3-Series sedan and coupé at Maker Faire Bay Area 2012 -- provides affordable and environmentally responsible electric conversion kits for the BMW E46. These are available directly to consumers but Electric Motor Werks is also building a network of installers (via tuner / speed shops) and setting up its own facilities.

We chatted with founder Val Miftakhov who gave us a tour of the prototype kit in the vehicles on display, so head past the break for more information and for our hands-on video.

Love driving but hate traffic? We hear you, and so do the people at Inrix. While the company might not come to the forefront of your mind when you consider the crowded world of navigation solutions, Inrix is a significant player in the field -- even if much of its presence exists behind the scenes. The company collects and analyzes data points from nearly 100 million sources, and now it's putting that information to work with Inrix Traffic 4 for iOS. In addition to helping users avoid congestion brought on by road work, police activity, local events and traffic accidents, the app now provides drivers with optimal routes and estimated arrival times for their two most common destinations -- a feature that's somewhat reminiscent of Nokia Drive 3. Inrix also leverages its data analysis to provide users with ideal departure times and even estimate traffic congestion throughout the day based on historical information. What's more, commuters can now quickly provide these estimated arrival times and routes to loved ones and co-workers via text message or email.

While the basic version of Inrix Traffic 4 is free, you'll have the option of upgrading to a premium version for $24.99, which brings traffic camera information and allows you to add more than two common destination points. We're told that Android users will soon find these features work their way across the aisle, although Inrix isn't yet ready to give a specific arrival date. If you're curious to learn more about Inrix Traffic 4, just hop the break for a demo video and the full PR.

Whether you're looking to replace a damaged screen, swap a battery, or just make damn sure that the warranty of your HTC One S is void, DirectFix can help with its latest teardown video. This is the first time that we've seen a detailed inner peek at the smartphone itself, and those who appreciate fine craftsmanship are sure to dig this one. To get deep within the phone, you'll need a nylon spudger, a Torx T5 and precision Phillips screwdriver, along with steady hands and -- if the display's adhesive isn't cooperating -- a hairdryer. Once the handset's back cover is removed, it becomes quite easy to see how the battery pack dominates the inner space, which is complemented up top by a blue plastic shield that includes the lens cover and protects the main board. From there, many fragile connectors must be removed before the display can be separated from the handset, which is attached with adhesive. Naturally, putting the phone back together can be a bit tricky in its own right, which makes it quite a shame that YouTube videos can't play in reverse.

When Amazon's Appstore initially appeared on the Android scene last year, one of its most innovative features was a Test Drive virtual machine that let users try out apps for free from their desktop, and now that technology has come back to the handset. In the newest update pushed today and pictured above, release-2.6.53 adds beta support for the cloud-based Test Drive feature to let users try out new software within the Appstore app itself. According to the description the feature is enabled on "select" Android phones and apps, although we didn't find any to try it out with on our Galaxy S II. Check for an update within the app to try it out for yourself or click the Appstore link below from your phone to snag the latest version.
