The app files may be in /system/app (and do actually appear to be readable without rooting) but the data is probably either in /data or /dbdata (which are not).
So, bottom line, this app's data can't be exported or backed up unless you root the phone? Any others like this?
I'm about to try updating to 2.2 using Kies, normally should I expect memo data to be preserved if this goes well? Most of what I need to be preserved is easily copied via SD, or synced to google.
Actually, I was really surprised that Kies can't generically backup app data (e.g. was implemented with the Palm Desktop). Huge bloated app, doesn't do much more than a file copy operation.
