If you are one of those lucky enough to already have your hands on the Nexus 7 then expect an update to be heading your way rather soon.
Google has started to roll out Android 4.1.1, build JRO03C which includes Google Wallet.
The update is also rolling out to Galaxy Nexus HSPA+ devices as detailed here on the Google+ Nexus page.
Jelly Bean makes everything feel fast, fluid, and smooth. Notifications are expandable and actionable, widgets are magical and the keyboard is smarter and more accurate: http://www.android.com/whatsnew/
Jelly Bean also features a redesigned search experience, with a new user interface and faster Voice Search. You can type your query or simply ask Google a question. Google can speak back to you, delivering a precise answer if it knows one, in addition to a list of search results.
Google Now is also part of the updated Google app, getting you just the right information at just the right time. Google Now tells you today’s weather before you start your day, how much traffic to expect before you leave for work, or your favorite team’s score as they’re playing. There’s no digging required: cards appear at the moment you need them most.
If you’ve got a Galaxy Nexus HSPA+ device, you will receive a prompt alerting you to the update over the next several days. Up next for Jelly Bean: all Galaxy Nexus, Nexus S, Motorola Xoom and of course, Nexus 7, which will ship with Jelly Bean later this month.
So, if you own a Galaxy Nexus the official update is on its way!!!!
