Although the Droid RAZR M hasn't been on store shelves for all that long, folks who picked one up may know there is an official Android 4.1 Jelly Bean update eventually coming to the device. Motorola hasn't said when, exactly yet but If you're looking to tinker around with it, there is now a leaked version of Jelly Bean available for download.
The file, designated as 'Blur Version.77.111.10.XT907.Verizon.en.US' can be flashed in stock recovery and comes in weighing 255MB but carries the typical warnings. If you flash it -- you do so at your own risk and there may be plenty of dragons ahead.
If you give it a go, drop by the Android Central forums and let us know how it's all working out for you. By the way, Motorola, now would be a good time to go ahead and add the Droid RAZR M to your Android Software Upgrade page as well.
