Leather-like finish

You do not have to remove the upper back cover as shown here too get the phone apart. Also the cover is held on by a number of small plastic pins that push into holes ont he grey part, and these can bend/break if not lined up correctly.

This simply llifts straight up to disconnect, allowing the board to carefully 'hinge' away on two other conector ribbons in the battery compartment.

I've had the same problem on two BJ-IIs, the center "OK" key (inside scroll/jog wheel) stops working, first no longer clicks, then it stops functioning altogether. Disassembled the phone to the point of the "cracking open" thread but can't figure out how the scroll/jog wheel comes off so I can get to the center key/button.

Any thoughts, tips or suggestions? Thanks.
