  1. Earliest "mobile" phones were used in WWII and were the size of backpacks (Developed by Motorola). Mobile phones have been around since at least 1950, but were attached to a vehicle (ambulance, police, etc), but were not connected to the telephone network. First Inventor of Cellphone was Rudy Krolopp (pictured) and it was the Motorola DynaTAC 8000X. It was unveiled in 1983, took 10 years and 100 million dollars to develop. They sold for 3,995 and weighed 2 pounds. First commercial network was the ARP in Finland (Known as the zero generation network, 0G) In the 1980s first generation (1G) networks were introduced. Some were SACS, NIT, and AMPS. The second generation (2G) started to surface in the early 90s. Today, we are in the third generation networks (3G), but the first 3G network was launched in 2001 in Japan by DoCoMo. Cellular Phones: The History
