Ok, I have hacked my Ipod touch before a while back with ziphone... but now im planing on buying a 8GB Iphone 3G from a friend brand new. I was wondering how and what do i need to do to unlock it to be able to use it with T-Mobile....Btw is there a way to obtain usage of the 3G network? and one more thing which plans do i need to get besides the voice plan.
