The Jelly Bean update roll out for the intel-powered Motorola RAZR I have begun. The first country to get the update notifications is France even though the smartphone was first launched in the UK.
All the usual goodies associated with Jelly bean are on hand including some new improvements to the custom Motorola launcher conveyed to you through the new firmware, version 4.1.2
You are much better off downloading the software over Wi-Fi but you can also use network data if you desire due to a file size of 300 MB. There is an automatic popup on your notification screen but you can check for it manually via the about screen on your settings menu.
The availability of the release should extend to other countries within the next few days or weeks at the most.
