So I was rather interested in the GreenPois0n Jailbreak since it will allow the iPhone to remain jailbroken even if you update it on iTunes. The thing is, is it completely permanent? Can it be overridden and ridden of? I ask because I'm concerned about the Voided warranty that's applied to the phone if it's jailbroken. I know that it can be restored which would remove most evidence of a jailbreak, but would it be possible to do that with GreenPois0n installed? I know it hasn't even come out yet, but was hoping someone would know the answer to my question. Thanks a ton.
