Scam. It's always a scam. There are only 4 groups of people that hack iPhones (Dev Team, Chronic Dev Team, RIP Dev team, Geohot) and none of them have released a jailbreak for 3.1 3GS, much less an UNLOCK.
How are you? This is my first post and i am happy to have joined such a great forum. I bought my iphone from the UK on o2 PAYG. However, as i live in thailand, True move have the iphone right to sell it in Thailand. Aint Apple suppose to unlock it as i am using one of their carriers?
