Good news to all Sony Ericsson Xperia users... Sony Ericsson has teamed up with Box to offer all Xperia users 50GB of free cloud storage! This is a limited offer and Xperia users must sign up before the end of the year to avail of their free space.
Simply download the Box Android app and sign up for a new account from a Sony Ericsson Xperia device. Although you get 50GB free, you do not get the advanced features of the paid service. (It's the 5GB free service + 45GB more space)
