Factory unlocking an iphone?

Could I get a iPhone (At&t) from the apple store online, and then factory unlock it through someone on eBay? I see the service all the time. A already factory unlocked black one is only like 200 on eBay, but I really want the white one which seem to be more expensive.

You can factory unlock any iphones on AT&T through @chronic on twitter. Ask him and he will tell you the price of it, he's safe. Not scam. Happy unlocking!

Well no one other than AT&T (in this case) can factory (permanently) unlock an iPhone. There are software methods but these go away if the phone is updated or restored.AT&T nowadays factory unlocks out of contract iPhones though.

I factory unlocked my iPhone 5 at http://www.iphonefort-mobile.com/. I'm now using my iPhone on T-Mobile and internationally when travelling. Unlock was done in a couple of hours. Good luck unlocking your iPhone. Celine provided me with excellent service.

Some of these answers are really funny. The best option is to get a permanent carrier granted unlock and probably the cheapest service for an iPhone that is locked to AT&T is available here: http://www.fastgsm.com/en/apple/apple/iphone-4/unlock/country-network

I'm using my iPhone with T-Mobile now after unlocking it at: http://www.iphonefort-mobile.com/
