An early build of Android 4.1 Jelly Bean has leaked out for Verizon’s Motorola DROID RAZR HD and DROID RAZR MAXX HD smartphones. The leaked 9.1.39 build is available to flash for advanced owners who are brave enough to put their devices at risk. Its stability is unclear at the moment, but the leakster claims “it’s fast and fluid,” it includes “many changes” and “Google Now works just fine.” Again, this is not the final build, so there are likely going to be some bugs and it may not be worth the trouble for average users, especially if you can’t flash back to an official stock build. Head over to DroidRzr for more details and warnings. Please proceed with caution.
