Google is rolling out the latest update to its open source mobile platform to T-Mobile's G1 and myTouch, setting in motion a busy schedule that is poised to see the OS arrive on a new crop of handsets due out this quarter.

Version 1.6 of the Android platform, dubbed Donut, coincides with a makeover of Google's (NASDAQ: GOOG) Android Marketplace, the online store for Android apps.

On the feature tally, Android 1.6 boasts an integrated camera, camcorder and gallery interface, updated voice search and other tools that make it easier to query various sources -- such as browser bookmarks and history, contacts and the Web -- directly from the home screen.

News of Donut's roll out arrives as Google's Android seems to be coming of age. In just a bit more than a year since its roll-out, the OS will likely be offered on three of the top four carriers in the United States, and on smartphones made by HTC, Motorola and Samsung. If rumors of a Dell phone coming to AT&T are true, Android would soon be included on all the major U.S. networks.
