Hi all
My sister just bought an iPhone 3GS off trademe and it is proportedly "locked" to the US AT&T network. The auction states that it is "easily unlockable for use in NZ". By this do they mean Jailbreaking with the likes of Redsn0w, which I have done quite easily on my iPod touch? If not then how is this done? Can it be done? Thanks for your help.
