hi there i got a iphone 3gs on 4.2.1 (8c148a) unlock and jailbroken but with baseband 06.15.00.
like everyone knows the gps dont work, is that any way to downgrade or upgrade the baseband or fix the gps.

i want to upgrade to the new firmware 4.3, do i have to use custom firmware or can i donwload from itunes, and can this version be unlocked?

There is currently no way to downgrade your baseband or get your GPS back.

If you want to upgrade to 4.3 you will have to use custom firmware because if you don't your 06.15.00 baseband will cause errors. Custom firmware doesn't include a baseband update so no errors.

Because you will still have the same baseband after upgrading to 4.3, Ultrasn0w will unlock your phone.
