No, one is GSM and one is CDMA, you cant move anything over. Also the ATT iphone has a problem with the HARDWARE's ANTENNA! Of fucking course the AT&T iphone is going to do worse, APPLE FUCKED UP THE HARDWARE which they have now spent over a YEAR to try to fix!
AT&T now has mobile to mobile to ANY cell phone on any carrier starting today included in the unlimited text messaging package, plus roll over minutes, and faster data speeds in MORE places than Verizon...Again, anyone thinking Verizon overall is a better option is smoking crack.
