Got an iphone 3G with 2.1 firmware officially unlcoked. THe phone can make calls normally, but can't receive any call, seems like the phone is out of coverage. Made restore to 2.1 firmware again, jailbreaked it with QUICKpwn 2.1, but the problem stilll remains. Outgoing calls are OK, but no incoming call, always unreachable! PLease any help friends!
