okay guys, try this to get rid of the Phone Incoming call issue:
HKEY_CURRENT_USER\Software\Microsoft\Today\Bubble then listed is BubbleBorderThemeImage, modify and delete the value

then:

HKEY_CURRENT_USER\Software\Microsoft\Today\Toast then listed is
ToastBoarderThemeImage, modify and delete the value

perform soft reset

I did this and I no longer see that bubble pop up on incoming calls..........the WM6.5 popup fix cab did not work for me
