This by far is no PA.What this does is give you what WM should have had in the first place which is Basic alert reminder function.
Led blink
Reminder alert every 2min
Reminder Vib every 2min is ringer is set on mute
For missed call/V-mail/sms/e-mail
There is icon to turn on and off with program status in
the carrier plugin.That simple.There is no conflict with OS = no headackes are had.No over throwing the OS here
