There is an official BlackBerry Messenger application coming soon to Android, but this recently published app called BBM isn't it. In fact, we don't think that this suspicious-looking piece of software would let you connect to the BlackBerry Messenger network at all. Allegedly, it works by downloading a BBM client in APK form, which then has to be installed manually by the user. Then the client would let the user send messages to specific BBM pins. Somewhat unsurprisingly, the software does not function, which is why it has collected tons of 1-star reviews, submitted by some of the folks who paid $1.49 to download it.
Needless to say, this app must be avoided. Actually, it shouldn't be on the Play Store at all, and we can only guess what kind of malicious code this self-proclaimed BBM application may contain. If you're impatient about getting BlackBerry Messenger on your Android smartphone, just wait until the official client's release. We'll let you know as soon at it is out.
