I can't say enough good things about Dropbox.
If I didn't have Dropbox, my phone would never have any space on it.
I regularly sync my photos to my Dropbox so that I can safely delete them from my phone to free up space.
If you could use some extra space, please feel free to use the link I've included to get Dropbox for yourself. If you use my link, and download Dropbox, they will give us both a free half a gig of extra storage space!
