Is there anyway i can find out if this iPhone 3GS is stolen?

I'm going to trade phones with some guy i asked him to give me the IMEI number so i can call at&t and verify that the iPhone 3GS isn't stolen but he won't give me it because he says its on his account? Any other way i could check?

I think you can check wether its been registered or not when bought!

Say dat he wouldnt do it
