We’re getting extremely close to the “by the end of summer” date Blackberry promised us when mentioning the launch window for Blackberry Messenger. If a couple of previous leaks weren’t enough to convince you, then perhaps this useless APK that leaked today is. That’s right — you can download Blackberry Messenger for Android and install it right now.

And no, I didn’t call it useless as a way of saying no one living in 2013 will care to use it (as many of you echoed in an earlier poll of ours). 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 Waterloo, Canada at this point.

We saw 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. Grab it here, poke it a few times,then let it rest as we await the real deal in the days to come.
