Over the years Motorola has established themselves as one of the worst manufacturers when it comes to releasing timely updates for their android handsets, especially those under the "Droid" moniker. They have recently pledged to bring updates to newer devices much faster than before, even going as far as to offer a $100 credit towards a new phone if they couldn't bring an update to a device you had purchased within the past year. We are beginning to see evidence of improvements. The Bionic has finally received its ICS update. The Droid RAZR M will be receiving Jelly Bean within the next several weeks, and now we have a Leaked version of Jelly Bean for the Droid RAZR HD! This is an early build and as such is not complete, but it shows us that they are hard at work to bring this update to our devices in a hurry.
The update is simple to install. You don't have to be rooted, but if you are rooted you will have to backup root with the "OTA Rootkeeper" app since the new root method will not work on Jelly Bean. It has also been verified that you can flash the ICS fastboot in RSD lite to return to stock ICS if you find this early version of JB to be a bit buggy.
