After you follow the instructions and get everything working, you need to update your APN settings under Settings > General > Network > EDGE > APN.

Tap the APN and enter the correct one for T-Mo. You'll find this by searching by your carrier name and APN over at Google.

Good luck! Have fun!!

Mike - Try the manual install. The GUI was rushed out. I did the manual install, couldn't get the part about the "bbupdate -v" or whatever it said to work, and it didn't matter, the unlock still worked. I thought this was a scam at first. I'm a AT&T and T-Mo customer (pleasure & business, respectively) and can verify the manual instructions work - I can swap around my simcards between my iPhone and BlackBerry (also respectively!). Hope this helps. Have fun! It takes about 25-30 minutes if you're patient. Good luck!

Just wait. It took about 25-30 minutes for me. If you're patient and wait it'll work!!!

Yes, it certainly looks like it works! Flawless!

iPhone killer is the wrong way to term this. StudioCITE is right on for laughing all the way off the edge of the page!

For the record, I'm a T-Mo subscriber who bought the iPhone on release day, ported my number to AT&T for it, and then canceled service with AT&T within 2 days of leaving T-Mo because of the call quality (the iPhone "echoes" only around my town; something with the local cell tower impacting service around here probably since my friends with AT&T also have the same problem and don't have the iPhone... also the call quality sounded slightly muffled and not as good as T-Mo everywhere else (T-Mo's is the clearest sounding phone I've ever used; I have the BB Pearl)... Not to mention the EDGE service - AT&T's is actually slower where I live than T-Mo, but not by much).

Don't get me wrong, I'm not bashing AT&T, they have suprior coverage (far better than T-Mo's). It makes sense T-Mo would have better sounding calls since their network towers have less traffic and users on them than AT&T's (re T-Mo being the distant 4th as noted).

WiFi calling from a hotspot for any carrier that would provide it allows you to use your cellphone handset for unlimited calling over WiFi without using any of your cellular minutes from your monthly calling plan. It's a nice added touch. Is it really worth an extra $9.99 per month though?! (What T-Mo charges to enable the service.) Probably is if you'd like to use your mobile at home vs. a landline; otherwise you'll be tethered to random hotspots if you're trying to save on cell minutes. Coincidentally, T-Mo's calling this optional WiFi service "@home". If you sign up you get unlimited access to all T-Mo wifi hotspots (Starbucks, etc.) as an added bonus (service usually starts at $20/month separate from the @home plan).

Personally, I'm not signing up for the service. The 2 phones T-Mo currently offers are a joke and are definitely NOT a threat to the iPhone nor AT&T (their 2 wifi handsets are more like DOA if you're comparing them to the iPhone). Maybe if T-Mo offers the service on a future BlackBerry it'd have more of a chance of threatening the new Apple-cart delivering all of the money that's been growing off trees since last week over at the new MaBell.

The unfortunate thing about AT&T is they will not give you an unlock code for any handset if you're traveling internationally so you'll pay more than $3 a minute for international calling while traveling ($1.29/minute for int'l roaming + actual cost of the call)... and in the iPhone's case about $10 per megabyte international data roaming fees (guess what, visual voicemail is a DATA service, not a voice service). There's no way to turn off EDGE while traveling anywhere (unless, like me, you cancel service and are left with a picture-taking, e-mailing, youtube-enhanced, internet-browsing WiFi multi-touch super-mini device... worth every last penny when the alternative is lugging around a big laptop just to be able to connect to the internet on trips...).

Yes, the iPhone is not in any danger!! I love mine (and love T-Mo's JD Power-awarded 1st class customer service and my unlocked T-Mo Blackberry Pearl) even without iPhone's cellular & visual voicemail functions!! Thank you Apple (my iPods, iMac, Mac Mini, and new iPhone), AT&T (activating my iPhone), and T-Mo (unmatched customer care & letting customers unlock their phone for international travel) for making all of this possible!

They'll make it if they dump their CEO, replace half of their managers, and completely outsource their customer "care" department, which was recently ranked at the bottom of a national U.S. customer service survey by Money Magazine/CNN. Sprint is near the only company in wireless who can do so bad (actually BLEED customers when all of the other majors are adding customers hand over fist) and not make any management changes... Their answer for everything is layoffs.

Enjoy your cheap data plan while it lasts. You get what you pay for (heaven forbid you have to actually call Sprint "care" to request any changes to your account or question your bill... Like me, you'll probably be hung up on 5 times, put on hold for 90 minutes, and never get any real service until you talk to the 6th or 7th "care" rep).

Whatever happens to them they will have earned it. They can still turn it around if they wise up fast.

Fugly

Maybe they're announcing they will be laying off another 10,000 Nextel employees.
