Bitcasa bills itself as an infinitely large drive that never runs out of space. In reality, you get 10GB for free, but infinite space costs $99 a year. The Bitcasa app is available for Windows 7 and 8, and there are specific apps for Mac, Android, iOS, Windows Phone and RT. Bitcasa says that you can get to your data on their Infinite Drive from any device with a browser. I can confirm that it worked on any mobile device I tried including a BlackBerry Z10 running QNX.
