    Default iPhone 4, 4.2.1 and BB 01.59.00 possible yet?

    I'm wondering if there is a way to safely upgrade an already unlocked iPhone 4 that is on 4.01 with ultrasn0w unlocked 01.59.00 - to 4.2.1, keep the untethered jailbreak, and keep 01.59.00 to keep my unlock?

    The dev team blog page hasn't been updated in some time - so I figured I'd ask here.

    There is no official untethered solution.

    It is possible to preserve the baseband if you "update" instead of "restore" in iTunes (and use TinyUmbrella)

    Do NOT try to "restore" with TinyUmbrella, it will fail and send your iPhone into a bootloop. Use the "update" option.

    Regardless, you will end up with a tethered jailbreak.
    Please read the stickies & search forum before posting!
