It's not often that Rovio's app franchise gets given away for free. There's a "LITE" version of Angry Birds available on your app store of choice, but that gives you a pretty limited look at why people love Upset Avians so much.
That's why you Android users should count yourselves lucky. Amazon's Android App Store just opened and to celebrate, they're giving Angry Birds RIO away for free. Yes it's the movie tie-in but that doesn't mean Rovio will hang it out to dry like its holiday offerings.
Head over to Amazon's app store and enter your phone number. Amazon will send you a link to their app and then Angry Birds will presumably be yours. You should probably hold on to the Amazon App because they'll be giving away apps for free every day. If you do get yourself a copy of Angry Birds RIO, tell us what you think!
