GameStop iphone/ipod trade-in policy?

I recently just found my iphone that was stolen ( iphone 4s). I found it with a changed passcode and without a sim card. Now i'm just trying to sell it to get an iphone 5. Will Gamestop buy it even though I can't unlock the phone? WORKS perfectly fine though

Call them.

You can't restore it in iTunes?

You can trade-in your iPhone 4S with NextWorth. They accept lackluster devices and will even wipe all the data so you don't have to worry about any information left on the device. Visit the link in the sources below to get a price quote for your device.
