farbod21, you seem to know a lot. I was just curious as to your opinion on which jailbreak is better? I have the 3Gs running 4.0.1 (8A306) with a 05.13.04 bootroom (I think). I try to follow what you guys are saying but this new jailbreak is a bit more confusing with the rest with everyone talking about TB and loading this and that, etc. I just want to upgrade my phone then jailbreak it.
