A cell phone requires a microprocessor to function. There is a great deal of overhead in the communication protocol that is not related to the voice transmission. But even the voice part has to be digitized. Chances are good that a design that relies on discrete components would be a cubic meter in volume.

You can look into cellular communications a bit further. Wikipedia has some links - http://en.wikipedia.org/wiki/3G

On the other hand, a wireless phone that can function at a small distance from the tranceiver base might be possible.
