Just got and loaded the firmware for 25.008 for the E6. Not entirely sure what it was supposed to fix, but it is certainly no faster, and the bluetooth problem (where the phone will not allow headset answer, but also will not allow answer through the keypad even to the handset) isn't fixed, so anything else is just window dressing.

It gave the catchall "stability" in the description, but I have to pull the bat once a day anyway to keep bluetooth going. Don't have any stability problems between bat pulls.
