my iPhone was on 1.0.2 FW i virginize it using i.unlock.no and upgrade to 1.1.1 after jailbreaking i install anysim 1.1 unlock it successfully but now my EDGE does not working in fact my carrier provides GPRS but it was working on 1.0.2 and i had no problem in this case safari says can't find server and nothing else like could not activate EDGE.
Did anyone face this problem?
and how can i fix it?
