I was really disappointed with Verizon and AT&T when I heard they opted out of the free 50gb dropbox promotion that European and Sprint users are able to take advantage of. As good luck would have it the good folks over at XDA-Developers have found a way to get past this little hiccup. There are a few different methods that I will be sharing with you.

The first method is to flash a rom that is based off of a carrier that is partaking in this promotion. Teleus, Rogers, Sprint and ect. A lot of members of XDA are having good luck with Diet ICS

The second method is to root your phone using The Samsung Galaxy Tool Box. It is similar to the Galaxy Nexus Toolbox I used before. If you want the Samsung Galaxy Toolbox please click here! After you have rooted your phone download this zip file

Follow the instructions in the text file. Also after you are done if you are a member of XDA-Developers go post in this thread and say thanks to Gamer113

I performed this and got my spare space.
