Hi,
I am using OZ 3.3.6-pre1 with opie 1.1.3
It crashes no more and comparable with 3.2 in the point of stability and very perfomant.
But it needs a lot of work to get it stable and you have to read a lot.
I am running Mediaplayer2, Scummvm, Latex, Hancom, jeode+apps, dviviewer, opera, wlan and a lot of other nice things on it and also moved home, root and opt to a 10MB/s SD Card.
Be carefull with update. I couldnt go back with the backup, but a backup from opie 1.0.3 was no problem for 1.13 to read (Addressbook, Calendar and Todo)
Cheers,
Sam
