My friend bought a used Iphone 3gs off a website, and he doesn't know the baseband or firmware version. It was stuck on the activation screen, but it would'nt read any SIM, the connector(hardware is fine) but when I checked the IMEI and ICCID it said unkown? I attempted a restore to IOS 5... and just when it was about to finish it gave me an error that it could not restore. So my next conclusion after researching various forums is that it had been unlocked/jailbroken and flashed to the IPAD baseband: therefore it wasn't showing the IMEI/ICCD. I also tried various methods of installing custom firmware using various versions of 4.xx, and redsnow, looked for ssh blobs but tiny umbrella can't read the phone. PLEASE help, I must be doing something wrong here, any ideas of how to restore/fix the phone? Thanks in advance.
