Android on Blackberry? Print E-mail

I've been browsing my Flurry stats for Screebl lately (an app that controls power-saving features based on orientation), and have noticed some interesting things.  One was the recent arrival of the Google Nexus One (or the "GPhone") as a user of Screebl.  That's exciting.

But I also recently noticed an entry for two different models of Blackberry.  What?  Has someone hacked android onto a RIM device, or is there a BlandroBerry in the works?
