Perhaps something very small (as in a grain of sand) is stuck inside preventing full closure. I would suggest you open it up using a guide like [http://www.ifixit.com/Guide/Repair/Installing-iPhone-3G-Logic-Board/575/1|this one] to get inside, and check that nothing's there, and then reassemble it carefully, making sure everything lines up and is flush.
