I've messed up my working 1.1.2 unlocked UK iPhone by updating it to 1.1.3 in iTunes (i know, its stupid).
After trying lots of methods i got my iPhone back to 1.1.2 jailbroken but the problem is that i can't use the phone functionality with TurboSIM.
For the info:
My iPhone was UK OTB 1.1.2 week 42.
Is there a way to fix this and get an working (with phone functionality) 1.1.2 or 1.1.3 ?
