Requirements: Android 2.2+, Rooted
Overview: Samsung has announced that that every consumer that buys and registers a Galaxy S III smartphone will get free 50GB cloud storage from Dropbox.
his is double of what Dropbox is giving HTC One series owners, however just like HTC, the free storage will only be valid for two years.
If you already have Dropbox installed on your Android device, you must Clear data, Force close and finally uninstall it from Settings > Applications > Manage Applications > Dropbox.
Thats installation for ClockWorkMod;
add apps here your internal sdcard and flash with CWM.
1.) Uninstall any Dropbox on your device.
2.) Download and install this :
3.) Login, and after about 10-30 mins you’ll get an email that says you’ve got 48GB of space more
İf you want to add manually , that’s way ;
