I just playing around this awesome apps "Dropbox" installed from the Market.
It work very good in syncing your apps,pics,videos,files and other kind of data.
1) Install dropbox applications in your PC and run it. You will required to create new user name and password for logging in. For free user you would get 2GB space. But space will increase if you invite others to joint dropbox.
2) In your phone, install dropbox.apk from the market and run it. Using the same user name and password you created earlier to login. You would see exactly the same folders listed in your phone dropbox app as in your PC.
3) Now everything you drop files into this drop box will be available across your sync dropbox. If you have two or three PC or three phones which all of them having dropbox installed. The same files will be available across each other.
4) You can share a folder to your friends around so every one of your friend would get what you wanted to shared with like music,apps,pics..etc..
Conclusion: You would litterally save phone memory space by having your files in dropbox. But you need internet access to access these files.
