On my replacement 900, the edges of the connector seem to be touching the cutout of the case. My first 900, the connector was completely recessed inside the housing. Again, only (4) small soldering points, and (2) larger, square, "glued" points. The USB pins also seem "glued", and not soldered. The contact points for the receptale's pins, on the board, are recessed. One would be hard pressed to clean them out, and re-attach, and expect to repair, if it does come detached.
