Ahh, the iPhone.
I understand your predicament, lol.

I have Sprint, and it's fine for me. Depends on where you live, I guess.
Anyway, look at it like this: the Razr and KRZR used to be reserved only for Verizon, and now it's usable with other providers.
So there may be hope for your iPhone yet.

Or get an iTouch for starters.
