Android 4.1, Jelly Bean, is now official and will become available in July. The first devices to receive it will be the Galaxy Nexus, Nexus S, and XOOM, if you aren't counting the Nexus 7 (our hands-on) which is already running it. After announcing it today at Google I/O, the Android team has posted the platform highlights, so that we can get a refresher of all of the new features.
