apr 3, 1973 - Cell Phone
Description:
The first cell phone was invented by Martin Cooper in 1973. It helps people because you can speak to people when there is an emergency and you need help. Also, it is better than a telephone because telephones have to be on a wire in order for it to work, but cell phones are mobile, so they work anytime, and anywhere.Added to timeline:
