Is there a way to stop the "different sim detected" message? I am using another family member's AT&T sim card in my iphone because I canceled the line that was originally activated with the iphone 3g. I have added the internet package and let the AT&T reps know that I am now using the iphone 3g with this line, is there anything else I need to do? My iphone is jailbroken and the software is version 2.2.1, I would like to keep it jailbroken if possible. Thanks in advance!
