I want to use iCloud but I'm still a little unsure how it will work for me. First, am I correct that it's not a full backup and it will not backup my music, videos and podcast? Second, I have my iPad setup with different apps than on my iPhones. Will iCould keep my iPhone and iPad app backups separate or will they be lumped together? Or is the app backup just backing up data and not the apps them selves since your supposed to be able to redownload them anytime? Third, is the 5gb free for each device or is it for all your devices total?
