Thread: iPhone 4 unlock not working
09-27-2012, 05:34 PM #1iPhone 4 unlock not working
I just bought a iPhone 4 with 5.1.1. Already with cydia. Ultrasn0w was already installed but my simple mobile sim isn't working. I downloaded the 5.1.1. Repo Fixer thing but nothing is happening. What am I doing wrong? I also tried putting in my old Gevey ultra s but it just says sim failure or invalid sim.

Who is your service provider? Ya best bet would be IMEI unlock.

AT&T, definitely get an IMEI unlock, either via link posted above or ebay. For the paltry sum, it is well worth it.
