Android users must really, really hate those green pigs -- Rovio Mobile, developer of the iOS über-hit Angry Birds, has tweeted that two million Android users have downloaded the app on that platform since it was released just three short days ago. The app has reached 6.5 million sales on the iPhone's App Store, but the Android version is a free download, supported with in-app advertising. The free "lite" version on iPhone has seen 11 million downloads so far.

Rovio has reiterated that a paid version of the app (with advertising removed) is still on the way, and its Twitter account also states they're working on QVGA support and support for other Android devices as well. No matter what they add in the future, two million downloads is a great way to start off on any platform.
