mfaizulislam asking: for Baseband downgrade , can it be applied to iPh4 ?
MuscleNerd replying: conceptually, yep probably. But new i4 unlock must precede that because otherwise, nothing to downgrade from 01.59 to
So, the dev-team is working now on downgrading iPhone 4 baseband 2.10.04 to 01.59.00 which is unlockable using ultrasn0w, but it should be known, that it has not been confirmed the success of this idea so far.
