Have JB 2.2.1 with 2.11.07 - how do I go to 02.28.00 to use yellowsn0w?

    Trying figure out a way to upgrade my baseband from 02.11.07 to 02.28.00 so I can use yellowsn0w. I am already jb on 2.2.1.

    Would prefer not to do a complete restore but will do that if necessary, since I need to use yellowsn0w.

    Some more information - I checked my bootloader version and it is 5.09.

    Any help would be very much appreciated as I am traveling now and would like to use the vodaphone SIM. Thanks

    If you want the "Easiest route", restore your phone with a stock 2.2 firmware. Create a jailbroken 2.2.1 with Pwnage Tool and restore that. You'll have a jailbroken iPhone with 2.28 baseband. I say easiest since you may already be familiar with these steps rather than attempting to update the baseband directly. :)

    Upgrading the baseband will work fine with any bootloader, it's when you try to downgrade (something that was never intended) that you need a vulnerable bootloader (in this case that would be 5.08).

    Actually I'm one of the few who has 5.08...but don't worry, it worked also on my 2nd 5.09 iPhone ;) Good luck!
