I am wary of using APT Backup, and I have lots of apps I have downloaded from Cydia and Installer, and I have my iPod Touch pretty much how I want it and don't want to start from scratch. I want to keep all of the settings and apps if possible. What files/directories are essential to backing up my iPod so I can restore them back via SSH after I upgrade? I know I don't need every single file on the iPod - do I just copy the files from applications and library? if I overwrite the library files will that mess with the upgrade? do I choose not to overwrite the newer versions of the default apps or keep the new ones?
