haha i've just asked the same question as you!!

Ya i want something like this as well for Maemo, i use SpoofApps for my iPhone and I use VirtualCaller & Fake Call on my HTC Touch Pro (Windows Mobile).....

VirtualCaller gives me the option to make fake calls as well as fake sms, which is nice.


Also, there're apps that can spam multiple SMS to your contacts, as well as sending flash sms.....it would be awesome if someone can make all this.....
