Hey guys. So I got my hands on a brand new iPhone 3GS, unlocked So what exactly do I have to do so I can put it on T-Mobile Pay As you Go? I'd want it so that I can just buy $25 PrePaid Card (130 minutes) every three months (Each card has 90 Days of Service). Would I have to just buy a SIM Card and put it in my phone? Or do I have to buy a T-Mobile Phone that comes WITH a SIM Card, and then activate the t-mobile phone, and then just put the SIM into my iPhone? Basically my question is how do I put the T-Mobile Service IN the iPhone, buy just buying a SIM and activating it, or having to get a Phone (from tmobile) with the SIM. Thank you guys!
