A good friend passed along the latest update for the Droid Bionic - 5.5.891. Being the adventurous types we decided to give it a shot to see what enhancements are headed our way. Well, to say the least Motorola has done their homework with this update and they have managed to patch root access and since there is not a way back it leaves us with an un-rooted Bionic until we/someone can figure out what they did to patch it and bypass it again. Until then our recommendations are to stay away from any updates until a root method has been found.
Aside from broken root we will check this update out and let you all know what we find.
