Since upgrading to this release the phone has now locked up several times. It never did this prior to this upgrade. Pressing the top button to bring up the "end current task" menu does nothing during the lockup, but I can at least ssh in to reboot (that's assuming, of course that I'm in front of my laptop). Something's not right.
Other than that I still have the at least one of the same issues as before (I wasn't expecting it go away yet, mind you): all three of my BT headsets randomly disconnect (two different plantronics models, and a jawbone). I'll report back any other issues I experience in time..
