Google has officially confirmed the Android 4.1 Jelly Bean update for the Nexus S smartphone. The details were posted on the official Google+ page for Nexus and is letting everyone know that the update has already begun rolling out. Perhaps more important though, Google has also offered details on which carriers will be offering the handset at this time. Bottom line, those sporting a Nexus S with T-Mobile, Rogers, H3G, O2 and Vodafone (in most countries) should be on the lookout for an update notification. Notably missing at this time, Sprint and the Nexus S 4G.
