Going back and looking at the Fab4 beta forum, the timeline looks something like this:
Dec 2008/Jan 2008: First beta units were shipped to testers. May 2, 2009: Firmware r5595 May 27, 2009: Logitech began shipping revised Touch models to beta testers and collecting the older 'PB1' units. Firmware version at this time was approximately r5907. I believe the first round of beta units were hardware version 4. I'm not sure about compatibility of newer firmware with those the early beta Touches. -- JJZolx ------------------------------------------------------------------------ JJZolx's Profile: http://forums.slimdevices.com/member.php?userid=10 View this thread: http://forums.slimdevices.com/showthread.php?t=90554 _______________________________________________ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch
