These are the bugs I have necountered so far. I will also be opening a TAC case on these bugs to hopefully expedite a fix:
ConfLst and RmLstC seem to reboot the phone after locking it up.
When user is in a conference, they press the ConfLst softkey to see conference parties. When they toggle to remove a participant, toggle then press the "Remove" softkey, the phone hangs. When the phone hangs, the user can do nothing - no phone keys repsond, and the cable must be pulled to force a phone reboot.
On top of it all, the party to be removed is not removed.
RmLstC does the same. If the user is in conference that he/she initiated then the user presses the RmLstC button, the phone hangs requiring a forced reboot or the party is not removed and the softkeys become dead - pressing them does nothing.
I've got more, but I'll spread the wealth instead with multiple discussions.
