The APK is actually quite useless as it won’t connect to Blackberry Services, the network used to push all these bits and bytes around in real time.
You’ll have to use it on a whitelisted device in order to get it to work, though we imagine there aren’t many of those running around far outside of Blackberry’s home country Canada at the moment
The application leaked on video a couple of weeks back, with one lucky user giving us a nice run through of everything we can expect. It’s full-on Blackberry, with the company’s design time ditching Holo for an experience that matches what you can find on their own devices.
You can download it anyway if you just want to check it out. download it here, poke it a few times,then let it rest as we await the real deal in a few days from today.
