I just got one and according to iTunes, it's running iOS 3.2.2 (7B500). I haven't updated yet. I used limera1n to jailbreak my iPhone4, but I hear redsn0w supports a never version of iOS? So what do I use to jailbreak?
P.S. I'm heading to Asia for a few months in 2 days and I heard that iOS 4.2.1 might not work with carriers there? What do I do?
