Just wanted to let everyone know that the hardware on the Lapdock 500 that was previously non-functional with the Bionic, appears to function now with Webtop 3.0 in the .2233 ICS leak. I have personally tested the webcam (it even emits a light), and the OS detected the Ethernet port so I have to assume that is working too. Have not yet tested the VGA port but will soon. Webtop 3.0 rocks. The bug with video being inverted when the phone is in the cradle has been fixed as well.
Update: Just tried out the Ethernet port and it works as well. There's actually an icon for it now in the tablet notification bar. Planning to try the VGA-out with a projector at work tomorrow, and will report back.
Update #2: Tried the VGA-out today and it works perfectly. F4 toggles the display just like on a Windows laptop. So all Lapdock 500 hardware is now verified to be functioning on the Bionic under Webtop 3.0.
