I'm still working to try to find investors for my ad phone service: The cellphone is free but instead of ringing, the phone plays an ad.

Now, who might buy advertising? One of the biggest ad buyers of all--mobile phone firms.

Instead of "beep-beep-beep" when a call comes in, you would hear a very short message saying something like, "Get a real phone from Motorola!"

My mother says she would use it.
