Back when Motorola announced the RAZR M, HD, and MAXX HD, they promised Jelly Bean before the end of the year. Looks like the M may be first on the list to get the update, because a leaked build (4.1.1/9.8.1Q_25/35) showed up online last night. We chose to hold off on posting, as Artem started this thread on XDA so we could get some feedback before telling users to flash a buggy or incomplete ROM. The initial reports have been good, so we feel comfortable recommending the ROM at this point.
As always, though, there are caveats to be aware of.
