I've installed beta3 into C3200, but the suspend/resume problem causes me a lot of troubles, and I ended up restore it back to Sharp rom.
I've had a 3200 for a week, running pdaXrom beta3. I also had suspend/resume problems, but finally realised that many of these were caused by me misunderstanding the screen blanking. The screen blanks after a couple of minutes, but I thought it had suspended, so I tried to resume -- but actually I was suspending it.
I've been following the practice below for a few days, and haven't had any of my previous problems:
* always suspend "properly" from the system menu
* always check that system really is suspended (not simply screen blanked) by pressing Shift key
* always resume by pressing on/off button for 1 second (and then wait)
I still have nuisances from 3-5 screen refreshes when system resumes, and a "whited out" label for the icon with focus in each directory. These are annoying but I can live with them. (Maybe they've been fixed in beta4?)
