I need to unlock my Samsung Galaxy S3 on Sprint so I can use it on AT&T. Help, please. Thanks.
Even if you unlock it, it will NOT work on AT&T because AT&T is GSM while Sprint is CDMA.
Basically, if the phone works on Sprint, it won't work on AT&T and vice versa.

GSM (AT&T, T-Mobile)

CDMA (Verizon, Sprint) it will work with Verizon if you unlock though.
