could be I guess. I use a Treo 650 and it did have a crash from Zlauncher early afternoon. But I have Plant tycoon running from an SD card so whenever I exit the app/switch to another program, it copies everything back to the Card.
Anyway, in an effort to try to prevent this again I wanted to make a copy of the save game. Problem is I can't find a file that would be the saved one - what is the name of the file??
