It has now been confirmed that the Nexus 4 will also be eligible for the free 50 GB cloud storage offered by Box.com to all Android devices in the U.S. . According to xda-developers senior member AP27, he had sucessfully upgraded the initial 25 GB offer to 50 GB after he downloaded the Box app and logged into it. There is however, a file size limit of 100 MB for this offer which probably mean that you will not be able to store your movies on the cloud storage.
So are you planning to synchronize the additional cloud storage with your Nexus 4?
