Here are the contents of an e-mail I have just received from Rovio.
"Angry Birds available for Android
IT’S HERE. AND IT’S FREE. After an extended period of beta testing, Rovio is proud to present Angry Birds for the Android platform. First of all, we’d like to thank you for your patience.
Why is Angry Birds free on Android? We want to make Angry Birds available for as many people as possible. Previously, many people were experiencing problems in finding Angry Birds on Android Market, but now everybody can download the game on their device.
Angry Birds will run on second generation Android devices and upwards, with Android platform 1.6 or later. Your device needs to support OpenGL ES 2.0. QVGA display resolution is not supported currently, but we will add support for QVGA devices soon.
Angry Birds Android features mobile advertising. A future update will include the option to purchase and opt out of advertisements.
To get the game now, you can download Angry Birds on your device for free exclusively from GetJar http://www.getjar.com/angry-birds. It will soon be available on the Android Market and Motorola SHOP4APPS, free of charge as well.
We have worked long and hard to ensure that Angry Birds gives the best possible experience on Android, and we believe we have reached our goal. We welcome our fans to see for themselves and have fun playing Angry Birds!"
I'm downloading it now.
