Life Cell-Phones Invention

There are meny inventions of this world, but not jest like the invention of the cell-phone.
I think that the cell-phone is the must important invention of the world.
Did you know that with the cell-phone, you can communicate with your family and your friends from faraway & different places of the world? Many years ago, that your parents were kids, there was not a cell-phone. What did you think they do to spend there time? Well, they were playing with their friends outside all day long, not just like us-sitting on the chair and talking with our friends from the cell-phone.

But there are many preferences to the cell-phone, like Internet, Facebook, G.P.S, camera and more...
The cell-phone, make our life easier, don't you think so?
