very nice trick!
my only question is, this is for 4.2.1 right?
the problem on 3gs (NB) 4.2.1 now is "thetered" when you jailbreak even you have lower baseband, so it still a problem
it's still better to stay away from 4.2.1 (for unlockers) so you can avoid thetered jailbreak problem and stay 4.1 and lower am i right?
btw,
again very nice trick sir.oxcto
i know this can be useful in some way
