jared have you checked the imei on this phone to make sure it isn't barred by the network? or insurance claims? that'd be the first place to check..it'll cost a few dollars online or a phone call to the network.

the other point to look at would be near the 'wing' with the antenna connectors on them..if the board has been forcibly removed you can get hairline fractures on the antenna circuit, the wing itself may be loose on that part of the motherboard. there are a few links on previous posts for jumping with solder when you find the crack, but I'd start with the phonecall. (usually you'll get 1 bar in signal and then it drops to searching or hangs when you try to call if it's lost/stolen/blocked.) try www.internationalnumberplan.com

personally jared I wouldn't touch that phone unless he supplies the imei and you've checked it... it's against policy to knowingly sell stolen goods... so if you buy it and it's cactus you are stuck with it. it's not a risk i take when i buy a phone... the resoldering of the prong is simple. the hairline fractures are a pain to find, but there's also a fix with a wire somewhere. For me the time to find the fault and fix it isn't worth it so I tend to avoid the "no signal" faults on ebay. I got stung by someone who sold me the phone and then reported it stolen, leaving me with a complete dud!
