iphone 3gs old bootrom jailbroken on 4.01 using jailbreakme.
looking to go to 4.1
recommendations please should i and if so will snowbreeze 2.0.1 work?
If I were you I would wait until the new jailbreak comes out. sn0wbreeze is dependent on a few things and seems rather complicated for what it is worth.
If you are already jailbroken stay with 4.0.1
