Requesting the cell phone manufactures / Cell phone service providers:
1) To make cell phones with the camera and the display on the same side of the phone. This would allow or make it possible to have video conferencing with the other person(s) called.
2) Make cellphone to be able to use Solar cells as batteries.
3) Better yet, make the cellphone such that just by moving it around the cell phone battery would get charged. (I know there used to be a wrist watch like that).
