How can I use Dropbox for iPhone and iPad backup and not iCloud? Both devices drove me nuts until I caved and increased my iCloud storage for backup.  I couldn't find a way to change default to my Dropbox account.  Please tell me how....
Tubedogg is right; there is no way to directly back up to your dropbox.  However, if you have your heart set on storing your backups in dropbox, you could back up to your computer and use a sym link to route iTunes' backups to a dropbox folder
