Since the other threads are growing to a size that's hard to navigate, I figured I'd start a thread for specifically addressing the initial impressions from those of us that have installed it and to also address what we know already. My initial impressions are: -This build finally brings the bionic to a point where it lives up to all the hype -Improved signal strength, on average about 5dbm improvement from 893 -Holds onto a 4G signal more reliably (haven't had a data drop yet) -Improved 3G/4G/Wifi handoff (almost seamless for me) -Stable and smooth -Battery life is outstanding! Now for what we know about the build: -It's a pretty extensive update that overhauls most of the components -It installs some more unnecessary bloatware, easily taken care of by freezing -Moto has officially acknowledged that they "accidentally" pushed this to a few users -This is the upcoming update that will be released when testing is complete -If you are 4ever rooted, you will retain root through the upgrade **For those of you that are all about the custom roms, there are working copies of Eclipse and Kinetix in the wild. If you are interested head over to Rootzwiki and check it out over there** Will continue to update as news comes available** Those of you that have applied this update, please feel free to add your impressions and if we find anything else out for sure, please add that also. I don't know why I didn't think of adding this stuff before, but here it is: Link for 4ever rooting: http://www.droidforums.net/forum/dr...70-r3l3as3droot-43v3r-root-bionic-v2-1-a.html Link for the 5.9.901 update: http://www.droid-life.com/2011/12/20/droid-bionic-receiving-mysterious-5-9-901-update/ (If the primary link isn't working, click on the mirror) Disclaimer: As always, neither droidforums or myself take any responsibility for anything that may happen to your phone when utilizing the tools provided. Albeit very unlikely, due to the fact that Moto accidentally released the 901 update to a small number of users, there is a very small chance this could remove you from the upgrade path. That being said, after applying this update, I could really care less if I ever get another OTA update. It's that damn good! There have been rumblings that the community figured out a way to get everybody back on the upgrade path. I don't know if anyone has tried rolling back from build 901 but either way, the limitless ingenuity of the android community has once again been demonstrated!!!!!!! This is with 4Glte and bluetooth left on for the duration. 2-3 hours streaming music via bluetooth 3 data intensive widgets on homescreens 1 hour of voice calls Probably about an hour total of surfing droidforums A few texts and emails Pretty fricking impressive considering that I wasn't trying to conserve battery at all. I can't wait to see how long this thing will run with battery saving in mind. One thing I still can't figure out with the bionic, is how much battery the bluetooth eats up. Out of all the other android phone that I've had, the bionic is the worst in this category by far.
