    hi guys, a few months ago i jailbroke and unlocked my iphone 3gs, i didnt need to unlock it cuz i already had at&t, and at the time i didnt know what blacksn0w was. now ive been reading some things that say some jailbreaks and unlocks modify your baseband. does this happen with blackra1n or blacksn0w? does this happen with any cydia apps? if so, does restoring an iphone restore the baseband? i look forward to reading your answers! thanks in advance!

    If you installed blackrain and then ran the unlocking tool then yes blackra1n modified your baseband.

    Put your phone in DFU mode and restore to factory spec. includes the baseband.

    Only Apple firmware updates will update your baseband.

    Pwnage Tool allows the update of firmware without updating the baseband (baseband stays at current level).

    Blackra1n does not update your baseband, but it is required that one updates to 3.1.2 firmware (5.11.xx baseband) to use Blackra1n
