Need a lil help jailbreaking and unlocking 3GS on 4.0.2

[Bobik]

can some one post a step by step how to jailbreak and unlock 3gs on 4.2.1 please.

Sorry, I meant 4.2.1

upgrade to 4.1 and unlock with redsn0w

 

[Bobik]

So jailbreak with redsnow and unlock with it too?

No. Redsnow for jailbreak only. Ultrasnow for unlock after jailbreak. Only if you preserve your baseband at 1.59.00...
