Android’s official code repository has been updated with a fresh load of Donut stuff in the past day or so, and as you might imagine, the dev community is already having a field day with it. Early reports show that all of the features demoed at I/O this year have made it into this cut in one form or another, including universal search, text-to-speech, and gesture support, allowing users to draw symbols on the screen to trigger actions. What’s more, though, the codebase is showing signs of CDMA support — a must for Sprint and Verizon, of course, both of whom will almost certainly have Android sets at one point or another — and a cool 5-in-1 bank of toggle switches in a home screen widget that can be used to control common features like Bluetooth and WiFi. Perhaps more excitingly, the community is hard at work on a couple major fronts here: first off, the Donut build is actively being ported to current handsets, and an Android Dev Phone 1 / T-Mobile G1 version is already available (though very, very crashy and incomplete right now).
