The official Android 4.1, JellyBean update for the Nexus S smartphone has began rolling out, according to a post made last week on Google's Twitter.
"We've started rolling out Android 4.1, JellyBean, to Nexus S phones on a number of carriers with more to come. Enjoy," tweeted the company last week.
Google also announced the carriers that would receive the Android 4.1 update first on the Nexus S smartphone that included T-Mobile, H3G, O2, Rogers, and Vodafone in most countries.
Other major carriers should follow.
There is also a ROM available that allows owners of the Nexus S to run Android 4.1, JellyBean on their smartphones.
The ROM seems to be pretty stable as people that have used it are reporting that everything works awesome on the Nexus S with it.
Anyone looking to install it on their smartphone should be comfortable with the process of rooting and flashing ROMs.
The Nexus S was released at the end of 2010.
Specifications on the handset include a 4-inch Super AMOLED display, 16GB of internal storage, a 5-megapixel rear camera, 512 RAM, a 1GHz Cortex-A8 processor, and 3G connectivity.
JellyBean debuted at Google I/O at the end of last month. The OS brings many new features to the Android platform, including a revamped notifications system, and the Siri competitor known as Google Now.
The software also features a redesigned search experience with a new user interface and faster Voice Search.
Google Now has the ability to answer voice commands and answer commonly asked questions such as what the weather will be, or how much traffic to expect, or even the score of a sports game.
The next devices expected to receive the software update include the rest of the Galaxy Nexus models, the Nexus S, and Motorola XOOM tablet. Those should upgrade in the coming weeks.
Android 4.1, JellyBean also comes pre-installed on the Google Nexus 7 tablet that the company started shipping last week.
