Alright thanks!!!

Alright thanks Bruce. The Chronic Dev Team is supposed to be releasing untethered greenpois0n soon tho, right??? And another question.....If I WERE to update, can I still back up my files in iTunes when I update considering my phone is jailbroken?? Won't that cause some sort of problem??

Sorry if this is a stupid question.....i'm new to jailbreaking. I jailbroke my iPhone4 with greenpois0n and im using iOS 4.1 I heard that this was a "permanant jailbreak", so I'm wondering if I can just go ahead and update my iOS to 4.2.1 or if this is going to screw something up...
