*UPDATE* - It looks as though PlayBook support was not intended for this app and BlackBerry World is showing it in error.
If you're looking for some additional cloud storage for your BlackBerry 10 device, you'll be pleased to know the official MEGA app has been released into BlackBerry World. MEGA developers have taken the Android version of the app and ported it over so it all plays nicely on BlackBerry systems.
MEGA is a secure cloud storage service that gives you 50GB for free. Unlike other cloud storage providers, your data is encrypted and decrypted by the client devices only and never by us. Your data is accessible any time, from any device, anywhere. Share folders with your contacts and see their updates in real time.
A lot of folks in the BlackBerry community have been advising the somewhat controversial owner of MEGA and active Twitter user, Kim Dotcom, that the app works perfectly fine on BlackBerry 10 for several months now. It's nice to see someone (@Kyle27_) got through to them and ultimately their developers to help get the app submitted. MEGA is available for all BlackBerry 10 devices according to the BlackBerry World listing, though you may need BlackBerry 10.2.1.
