Looking for massive online storage for free? Here's a trick. It expires at the end of this year so better be quick.
Sign up for an account at
Box | Simple Online Collaboration: Online File Storage, FTP Replacement, Team Workspaces to get 5gb free.
Afterwards simply install this app on your phone and run it:
https://market.android.com/details?id=com.redphx.boxnet
It basically pretends to identify your phone as a Sony Ericsson so that you instantly get 50gb for free. (Sony Ericsson and LG have a promo that gives them free 50gb storage at box.net) You can uninstall the app afterwards and if you're worried about the app collecting your info simply change your password afterwards.
There's also a box.net app for android but I haven't tried it yet.
