Google's Android 4.1 Jelly Bean mobile operating system was officially unveiled at Google I/O 2012 just a couple of weeks ago, and it looks pretty fantastic. If you've been hoping to get your hands on it and your the owner of a Samsung Galaxy Nexus HSPA+ smartphone, it's time for you to rejoice--the Jelly Bean rollout has begun for you! Do note that this refers to Galaxy Nexus devices that run on AT&T and T-Mobile networks. Owners of the Verizon Wireless Galaxy Nexus will have to wait a bit longer. The Nexus 7 tablet, Nexus S, and Motorola Xoom are next on the list to receive Android 4.1 goodness.

Anyone start playing with Jelly Bean yet? Feel free to sound off in the comments.
