The Amazon App Store for Android was released today and it brought along Angry Birds Rio for the ride. Even better, Angry Birds Rio is free for a “limited time”. We haven’t yet heard what that limited time is. The app store can be downloaded from here. It’s a pretty fast download and install, but before you get started you will need to navigate your Android phone to Settings => Applications and enable “Unknown Sources”.
The app store looks similar to the native Android Marketplace and carries a lot of free apps, in addition to the paid ones. You can browse by a variety of categories such as Top, New, Games, Entertainment, News & Weather, Social Networking, Etc.
The store contains all three versions of Angry Birds (including Rio which is exclusive). Other apps such as Fruit Ninjas, Audible, CraigsList, and IMDb are also included.
The menu button, again like the Marketplace, allows you to check you apps, Search, view Reommended, and several other options.
You can take a quick tour of the screenshots posted below.
