no, they are the exact same phone just with different carriers.
Verizon wireless and at&t
AT&T as of now, rumors are Verizon 2011.
Yes, the iPhone is a cell phone provided by AT&T and Verizon Wireless.
No, V Cast is a service of Verizon Wireless, the iPhone is currently exclusive to AT&T in the USA
No No NO!!!! At&t is Verizon Wireless's competitor... it is no way part of Verizon wireless.
Verizon because you can call at more places with a better signal.
yes yes it is :)
Apple and AT&T made a buisness deal a few years ago, and as you may know, AT&T and Verizon are one of the biggest rivalies in the wireless phone buisness. And, the iPhone is designed for AT&T service, and you need a SIM card for the iPhone, which Verizon doesn't have. So the answer is no.
No, and yes, sadly. Dumb AT&T are keeping it at 3G, unlike Verizon and T-Mobile. If you really want 4G on your iPhone, then get the Verizon iPhone 4. Much better.
At&t or the apple store (it might be coming to Verizon wireless but not now)
In order from greatest to least Verizon wireless, tmobile, at&t, attel sprint nextel
It is not possible, due to the fact that AT&T is a type of network called GSM. It is not compatible with Verizon, a CDMA network.
