It's been quite a while since we heard about good old BlackBerry Messenger on Android. The last we heard was that a test app from RIM was over in development over a year ago, and though RIM has grown closer to Android through its Playbook tablet, that doesn't mean they're any fonder. The rumor fell through in the months since. In any case, TechnoBuffalo has got a photo of what looks like BBM running on a Froyo or older device. Someone's trying out the idea, but there are a few warning bells to consider.
