Oh how I wish more cell phones had similar functionality - even if through 3rd party software. Toysoft development has created an interesting and functional little application for Treo users by the name of Fakecall.

Fake Call is a program that is intended to give Treo 600 owners a way to escape impromptu office meetings and unwanted social interactions using the Treo — by simulating incoming phone calls! With your phone in your pocket, press and hold a hard key or setup an appointment in the Contacts application and voila! A call will materialize from anyone you want, your phone will light up like a Christmas tree, your faovirite ringtone will sound and, when you accept your fake call, an active call screen identical to a real one will display and a voice will be heard on the other end of the line! This program is a true escape from any unwanted situation!

For about $6, Treo users can setup their handsets to receive a fake phone call. This goes above and beyond setting your handset alarm and assigning a ring tone.
