I have an AT&T IPhone 5 that I want to use on a Verizon service. Can I do this? If so what do I need to do?:concern:

Bottom line: You can not use a device that was OEMed for AT&T on Verizon. Verizon will not do it because of device compatibility needs of their legacy CDMA network. Sell your AT&T version and buy one that was originally OEMed for Verizon.
