Getting random shutdowns as well. I have uninstalled ALLOT of 3rd party apps but cannot find a culprit. One thing I did notice was that I had my phone for 3 weeks, using the standard battery, never had a shutdown. Got an extended life battery while in Vegas a couple of weeks ago, have have 5-6 shutdowns since. Very annoying. While I am generally happy with the Bionic, this with Apps saved to SD card disappearing, I am starting to wonder if I made a mistake. Keep hoping there is an OTA to fix some of the problems.
