I HOPE THIS IS A JOKE.
Verizon and Sprint SUCK!
They are CDMA Networks. WHY would a prestigeous company like Apple want to partner with a crappy CDMA-based cell carrier? Verizon and Sprint are the absolute worst. The reason the iPhone is on AT&T is because it is the only network suitable to handle the demands of the iPhone.
And for all of you people who have reception issues, get out of the 2% area that AT&T hasn't reached YET and move to a bigger better city like Philly who has absolutely no reception loss. I have no problems with my iPhone. EVER.
So stop complaining. You don't need an iPhone if you're going to moan about it.
What a ridiculously ignorant post.
