A little bit Gingerbread, a lot Honeycomb, the next version of the Android OS, Ice Cream Sandwich, was officially announced today at Google I/O 2011.

Ice Cream Sandwich will replace both the current smartphone and tablet iterations of Android for a more unified “One OS Everywhere” user experience across all devices. The UI is said to be a mixture of Honeycomb, the version of Android found on late-gen tablets like the Motorola XOOM, and Gingerbread, the latest version of the OS running on smartphones (though not on as many as we’d like).  Specifics were nowhere to be found.

And there were no release details, either.  But you can bank on the fact that the OS will be rolled out slowly (or very, very, very slowly) sometime in the coming months.
