Re: Please respond with reasonable answers -- how I would like to change the *digital* cell phone industry.

I would have the wireless phone do VOIP on universal wireless internet,
accessible everywhere.

I have felt that there should be provision in all future wireless base units
to relay the internet "cell" signal to other devices as a background
activity. This would expand the connectivity penetration.

By cell, I'm not referring to the existing cellular phone network.

Phones might also be relay points during calls, when they are using their
battery to transmit anyway.
