I believe that you want to activate an iphone
with metro pcs, right? Well, if that's the case, you're in the same situation I'm in. I want to know if I can activate an iphone with simple mobile. And also how can I unlock an iphone if I buy one. But back to your question, I strongly believe they,(Metro PCS), can activate it for you. I'm telling you this because I know someone who bought a blackberry phone on e-bay and went to metro pcs and activated it the blackberry phone. And guess what?... he's only paying $40.00 a month and still enjoying all the blackberry features! So, go to a metro pcs store with your iphone and see how it goes. Good luck!
