When Android 4.1.2 hit the airwaves for upgrades, it was limited to a very exclusive club of Nexus 7 owners. Google has widened the gates considerably as of today: we're receiving multiple reports of GSM-based Galaxy Nexus and Nexus S owners getting the new Jelly Bean build through official, over-the-air channels. Upgrades here aren't as noticeable as they are on the reference Android tablet; besides fixes, we've mostly heard that it's now possible to expand a notification with a single finger. Those with CDMA-based phones are left out so far, but if you discover any surprise extras before 4.1.2 hits our own devices, be sure to leave us a tip.
