That's a photoshop of the really old phone (before cell phones) combined with a new cell phone. One of the first cell phones were the size a of a briefcase! They became popular when the were reduced to the size and weight of a brick. Cell phones that take pictures/video have only been around for the last 3-4 years.

i know, i was trying to be one of those new-technology kids who only read books for their new video games
