just would like to mention my needs, and unfortunately I cannot satisfy 
them with your project. I would even tell, I don't have a need for voice 
communications. But if I were, I would use something over Internet, like 
So I don't need a "phone", but a mobile computer, which may benefit from 
having a microphone and speaker.
Also, routing voice traffic through the Intrenet is a way to not be 
obliged to pay to carrier per minute or per text message. I think that 
carriers earn too much money just because not all the people still used 
to Internet.
I prefer getting a data plan and pay monthly, while using encrypted 
communications for mail and chat.

So I use gprs only in order to have Internet. Not to call or receive 
regular calls. I believe, if we get Internet, then we can manage the 
rest without carriers.
