I read a few posts about backing up data from apps like weather or stocks, but recently I re-installed operating system due to hard-drive corruption, which meant I had to reinstall iTunes; now iTunes thinks I have a new library and when I attempt to sync, it says everything on my iPhone will be erased and replaced by whatever I'm syncing. So I'm planning to let it sync, then after syncing move back everything that's backed up. What would I need to copy in order to backup everything on my iPhone, including all installed/downloaded Cydia apps/tools/etc, all app/game data, music, videos, and others? And please show me how to do it. Thanks!
