Users of Motorola Droid Razr M will welcome the upgrade news as just two months after its release, the smartphone is about to get the Android 4.1 Jelly Bean OS.

On Friday, Nov. 9, Motorola announced on its Twitter page that it has started rolling out Android 4.1 update to Verizon Droid Razr M users.

"Announcing Android^TM 4.1 for the DROID RAZR M BY MOTOROLA, now rolling out in phases," read the Twitter post.

The OTA update is rolling out in phases and it will take few days before Jelly Bean becomes available to Droid Razr M users nationwide. The new software update will bring with it several new features.

"We're excited to announce that DROID RAZR M is getting upgraded to Android 4.1 Jelly Bean," read Motorola's blog post. "Jelly Bean includes a number of fantastic new and improved features, including Google Now, Voice Search, and improved notifications."

Verizon, on the other hand, also posted a support document (PDF) on its Web site, instructing users on the steps to update their Razrs to Android 4.1 Jelly Bean. As described in the PDF file, the update is 254MB in size. The update will take up to 30 minutes to download, depending on network conditions. Moreover, it will require additional 15 to 30 minutes to install, during which users will be unable to make or receive calls using the device.

Android 4.1 technically isn't the latest version of Android operating system anymore; blame Android 4.2, which is still named Jelly Bean. Motorola didn't provide a date when it will update the Droid Razr M or any of its existing Android devices to version 4.2, but promised to give a sneak peek into the latest version Android with its upcoming Test Drive program.

"We're also introducing Test Drive, a new program that will allow consumers to take our major software upgrades for a trial run and provide valuable feedback before we launch the upgrade publicly. Starting with Android 4.2, the next iteration of Jelly Bean, we will release a preview of our software to a few hundred consumers that sign up for Test Drive," Motorola added.

The Droid Razr M is the second device from Verizon Wireless to get Jelly Bean after Samsung Galaxy Nexus, which received Android 4.1 update in September. According to Motorola's Android Software Upgrade page, the company will bring Android 4.2 only to two more smartphones - Droid Razr HD and Droid Razr Maxx HD - in 2012.
