More news are coming out of HTC’s keynote event in Barcelona for MWC 2012. The firm shared promise rings with Dropbox a few months ago, offering 5GB total storage capacity on its Sense 3.5 devices, and now the two companies are ready to take the next step in their commitment with ICS-backed version 4.0. This time they’re integrating the cloud service directly into its OS and are offering five times the storage for free, up to a grand total of 25GB — in addition to the amount you already have in your account — for the course of two years.
