How to Unlock AT&T iPhone 4 to work with Verizon?
Either posting a link to a tutorial or writing a tutorial yourself will work! AT&T to Verizon only! Not Verizon to AT&T.
Its not possible, the AT&T iPhone 4 is a GSM only phone
Verizon is a CDMA only network, and these devices/services are NOT compatible.
You can unlock your Iphone 4 from AT&T but you can't use that with Verizon because it is a CDMA network. You can't use CDMA network with your GSM mobile. Use remote unlocking service to unlock your Iphone 4. Get the code from the site http://www.onlinegsmunlock.com/apple-iphone-4/rs7wp9/, and unlock it using unlocking instructions.
AT&T phone's not going to work on Verizon. Period.
I have used http://www.officialphoneunlock.com 's services. I think they IMEI unlock your iPhone.
They seem to be experts and have been able to unlock my iPhone 3Gs and my iPhone 5.
My friend unlocked his iPhone 4 via them aswell.
