I know this is not possible. I work for an agent of Verizon. I get so many people wanting to put an AT&T iPhone on Verizon. This one girl said she bought software that Apple uses to unlock her 3GS iPhone. www.iPhone-unlocked-pro.com. She paid $24.99 for the software. I just don't know what else to say, but GSM....CDMA....GSM....CDMA.
