Google has announced that Android 4.1, Jelly Bean, will be rolled out to the Galaxy Nexus, Motorola Xoom, and Nexus S via an over-the-air update in mid-July. That's a major departure from Ice Cream Sandwich updates, which took far longer to get to the Xoom and the Nexus S. Unfortunately, it isn't clear if this update schedule will apply to all versions of these devices — we've certainly seen before that carrier variants of Nexus devices can see a much longer wait than their international and unlocked brothers. The Sprint Nexus S 4G is the prime example: it didn't get updated to Android 4.0 until April of this year — many months after the Galaxy Nexus launched with the then-new operating system. Be sure to check out our complete rundown of Android 4.1 to see what you'll be getting when the update arrives next month.
