Thread: Downgrade

    Default Downgrade
    Hey guys. Still a newb here so take it easy on me

    I recently upgraded my 3GS to the new iOS 4. I am putting my phone up for sale and I feel that I should downgrade back to previous firmware so that it can be unlocked by potential buyers.

    Is this as simple as downloading the previous firmware and doing a customer restore in iTunes or is there much more to it than that?

    Any help is greatly appreciated!

    You got there with a custom firmware? Then yes, just use a custom 3.1.2 or 3.1.3 firmware.
