Google just released the source code to android 2.2 “Froyo” today, and it is now available for download via their site. This probably kicks off the countdown to an official build of Froyo as an OTA update for other android phones, such as the Evo 4G and the Nexus One. Head over here for a 2.2 source code download if you’re into cooking your own roms! The 2,2 sdk, which has been available for a while already, can be found here.
