i have an att iphone 4, finally got att to unlock it and confirmed working on tmobile
after about a day it doesn't recognize the tmobile sim or att sim, both working phone lines
before this i noticed that the wifi option was greyed out and that leads me to beleive the phone has a hardware problem
now am i missing anything i have restored it and it won't get past activation keeps telling me there is no valid sim, when i am 100% sure the att sim i have is valid since its my line that i use on my own iphone.
