    I have a jailbroken iphone 3gs on 3.1.2 firmware. Can i upgrade to whatever the latest firmware is? if so how? i don't need it to be jailbroken anymore.

    Yes, but do you want to preserve the baseband, required if you want to unlock the phone? If so, then you will want to use Sn0wbreeze (Windows) or PwnageTool (Mac) to make a custom firmware and flash that.

    FWIW, even if you use AT&T and do not care about preserving the baseband... if you preserve the baseband, your phone will have at least $75 higher resale value due to being unlockable (in my experience).

    +1. I very much agree. You should upgrade with a custom firmware.
