My iPhone 4s lost its imei - can I put it back?
Need help
My iPhone 4s lost the imei.
Enything is still working besides recognizing any sim card. It is not recognized by any computer as well. I already went to two labs in Israel, but got it back not fixed.
Really do not know what to do and who can help me.
Not installing firmware update and not erasing all data are successful.
iPhone 4S, iOS 5.0.1
