I was browsing around for some cool new apps for my DX and I came across dropbox, and wow this app is awesome. It creates a folder on your desktop that basically is a 2gb peice of cloud. You can put anything you want in there, and organize it how you like, and it will instantly show up on the dropbox app on your phone, works across multiple computers as well. Its so great for transferring music, videos, and other files on and off your phone quickly and easily.. Best part is its free!
Use my link to sign up and you'll get an extra 250mb of space too:
Let me know what ya guys think
