1.1.2 ---> 1.1.3 by Apple Store - Invalid AT&T Sim Issue...
Here's my problem:
I was given a phone with 1.1.3 installed and I was told by the person who gave it to me that the Apple Store Rep, before giving it to him, put it on a cradle and updated the software to 1.1.3.
My guess is that it was an upgraded OTB1.1.2... I downgraded to 1.1.1 and via ssh checked BL and returned 4.6 while on 04.03.13_G...
After doing this, the phone does not even accept the original AT&T sim that came with it! I keep getting an "invalid sim" message!
I updated to 1.1.2 and JB and I am now going to go to 1.1.3 just to see if this fixes the problem.
Any ideas? THANKS!!!
