I was wondering, has anyone seen a .sis file that would open a specific flash
file on certain phone events like receving a message, phone ringing, or when
the screensaver would invoke? (or is there a way to do this natively in the OS.
can't seem to find it.

I had a question previously about capturing incoming sms. Maybe the *.sis file you're looking for may help my dilemma.

Justin, kindly let me know if you've found such file. thanks! :)
