Disable Dialing #777 and Sent Text Message Notification
 

Any way to do this?

I thought I read about it before my device came and now I can't seem to find it.

disable #777 by going to start/settings/sounds and notifications/notifications/event is connection established, and uncheck the display on screen message. as far as the text sent....theres a reg edit for that....check the wm5 hack list thats a sticky in the htc apache forum. it should also work on the treo. hope this helps.
