Ok i have a new iPhone 3gs running 3.1.3 firmware, locked to the o2 network. I use the o2 network anyway, so that is not a problem if it updates to the network when i jailbreak, right? Also because of this, is there any risk when i jailbreak to 3.1.3 with snowfreeze or whatever it's called? Many thanks in advance, its running the newer bootrom. Or should i just wait till greenpois0n comes out?
