This is a great app to have on your phone, especially if you use Titanium Backup premium. You can synch your backup files (or any files on your phone- pictures, documents, even texts (I think), etc) to Dropbox and access them from any computer with Dropbox installed.
I highly recommend this app. If you want to install it, please use the link here- it will increase the size of my Dropbox account if you sign up using this link (and I need the extra space for work and IncForum/ Android files). Later, we can put someone else's link up here and increase their Dropbox size.
Always have your stuff when you need it with @Dropbox. 2GB account is free! http://db.tt/HoSD4mF
