    Hi all

    I have an iphone 3g on 3.1.3 and I want to unlock and keep the GPS I have tried to restore it to custom 4.1 and 4.2.1 but it fails on both times.

    It is now stuck on the itunes cable logo and it will not exit recovery.

    I really do not want to restore it to 4.1 as Ill have to use the 6.15 badeband

    Any help would be great

    thanks in advance

    A custom built 4.x firmware restore with Pwnage or Sn0wbreeze will preserve your baseband and unlock.

    Apple is approving 4.1 today, so it's no problem. If you have SHSH blobs, then other 4.x iOS versions can be restored too. So .. if you use a custom built firmware ... and ... have SHSH blobs, you can restore any 4.x firmware and preserve your baseband and lock.

    On a 3G iOS 3.1.3 is the best. Any iOS 4.x is sluggish and slow.
    Newer apps will run, but likely you won't be so happy.

    Note: If you always load a custom 4.x firmware ... the iPad 6.15 BB is not required on any iOS version

    Note2: Ultrasn0w unlocks 3.1.3 baseband, so a custom firmware is not required.

    thanks for all the info its back on 3.1.3 and am jailbreaking it now with jailbreakme.com.

    I have shsh for 4.1 and 4.2.1 and I did a restore with apple using custom firmware and as I said it failed both times so maybe I need to do a restore with TU ???

    What iTunes error?
    If 1015, use Tiny Umbrella 'exit recovery'

    Also, restoring 4.2.1 requires one more thing. TU + TSS server running before starting the restore.

    We recommend 3.1.3.

    If you need 4.x compatibility for some apps ... then it will be slow.

    You get to choose what is more important: speed or apps
