I use a PalmOS app inside Classic on the Palm Pre to store some data. Is there any way to back up the data?
Use Red Feline Backup - VFS Backup for Palm OS
Red Feline Backup is a backup program for PalmOS. It does not require a host PC. Instead all databases on your PalmOS device will be copied onto a memory card inserted into the device. then you can copy from your memory card to host PC
