I have a new 3Gs & it's on AT&T. My iPhone is already at 3.1.3 what I'm wondering is if I take it to Telkomsel (indonesia iPhone carrier) can they unlock it from AT&T so I can use their network ? I know illegal in the USA but Here in Indo it's very corrupt so a few bucks can get a lot done. So is that possible to do ? or am I out of luck ?
