I don't want to be negative, as it's really a good idea to have more battery power, but I can't wait to see what wrapping a lithium battery around the iPhone's GSM radio antenna will do to its already iffy reception, never mind its GPS function. This thing should kill reception and transmission power on the iPhone, if only looking at it logically. It's a great idea, as long as the iPhone doesn't suffer signal reception or transmission degradation. We'll see what further testing reveals. That's my 2 cents.

Why waste space reporting this crap, Engadget? Who cares?

Invisible Shield may offer great protection for your device, but if you keep your iPhone in an incase case on your belt, for example, the black case discolors the plastic on the Invisible Shield where the phone makes contact with the case, making it look very unappealing. Besides, with time, the film yellows and makes the back of the iphone look like crap. She Invisible Shield discolors very easily, something all of you who think this stuff is GREAT, have missed. Yeah, it'll protect the iphone from being scratched, but in the end, it'll look like crap. I ripped mine off the phone and called them for a refund, but all they offered is a replacement of the same crap and admitted that the film does discolor after a while..it picks up dyes from your jeans, your backpack, your belt clip...anything. It sucks. Find another way to protect your iphone and other equipment before you throw your money away. You've been warned.

I think the "radio" you're seeing on the iPhone is for the GSM radio and not necessarily an FM radio option coming down the pike.

Not too bad! This is great guys. I can certainly put this awesome HTC device to good use. WinMob6 rocks! Engadget Mobile is a class act. I hope I win it. I'll even send you guys a picture of my ugly mug making my first call on the unit so you can post it. Thanks Engadget!

This I-Mate Jamin is a real POS. If you're considering buying one, forget it. It totally sucks. It turns off by itself. Resets for no reason by itself. You can't use an SD card in it because you'll see the PDA reset itself every 5 minutes. The radio turns itself off with no warning a few times a day. You don't get your calls. It's slow as hell...the slowest device other than the KJam I've ever used. I've done soft resets, warm resets and countless hard resets and the phone is still the same. I have no software loaded on it other than what came with the Jamin and it's still resetting. It has a mind of its own. I've owned other HTC products like the K-Jam and the Treo 650. They're all JUNK. Stay away from HTC and its rip-off players like Imate, Qtek, Dopod and others.
