Purchases a very cheap 3GS from ebay. Was listed as unlocked but also needed a new logic board because the device would not turn on. I took my chances and bought it. I charged it a bit put it into dfu mode and itunes recognized it and reinstalled 6.1.3 with no problems. Went to set up and will not activate. I tried an old att sim and also a t mobile sim. I was able to pull the imei number and on iphoneimeiinfo dot com it says the phone is locked. I'm also seeing that the iccid number says unknown. Any ideas? One last thing. After restore when I plug into iTunes it starts reading that the phone is attached and has a little spiny wheel then itunes crashes. It never gets to the point where I can view the iphone info.
