| i hade the same problem on iphone 3g. was v3.1.2 and updated on itunes but was updated to 3.1.3 and modem sw 5.12 and i was not able to unlock it.
after a lot of struggling i managed to install v4.1 on the phone and unlock it with redsnow but also no network.
after some searching on this forum i updated the modem sw to 6.15 and rebooted the phone twice and it got network.
good luck with it and with the searching!!! |
