a friend and my brother in law bought iPhone 3G from Singtel Singapore and after in-store activation, I can put any sim card in his iphone. my friend tried M1 Singapore and works. I've tried inserting Telkomsel (Indonesia) and roaming works, voice call and sms tried Optus Australia and roaming also works, voice and sms I wonder if actually the iphone is unlocked but only need to bypass the activation process? does pwnagetool do this? the current version loaded is 2.0.1, if i update this to 2.0.2 i need to activate it again right?
