Hi, i have one iphone 3G that my friend gave me and it is having "no service" problem. I restored it with 2.2 firmware and jailbreaked it with quickpwn. It is now running on 2.2 firmware and 02.28.00 baseband. I unlocked the piece with yellowsn0w 0.9.8....but still no service!! any ideas how i can repair this piece?
