Ignore Call Via SMS Comes to the Treo 650
SharkMsg is a new app that brings an innovative new feature from the Windows Mobile Treo to the Palm Treo 650 that Palm and Microsoft said couldn't be done on the Palm OS. SharkMsg prompts you to send an SMS to the caller when you ignore an incoming phone call allowing you to decline a call with a friendly text message.
Palm first demonstrated this feature with the Windows Mobile Treo. Microsoft Senior VP Pieter Knook remarked, "A feature that Palm had been unable to implement with Palm OS enables users to decline a call with a friendly SMS, signaling “In a meeting” or “Talking with the boss” instead of simply ignoring the call."
