According to Wikipedia, the first handheld mobile phone weighed 4.4 pounds (2kg) and was demonstrated by John Mitchell and Martin Cooper of Motorola in 1973.

10 years later, in 1983, the DynaTAC 8000x became the first commercially available cell phone. It went on sale in the United States in 1984 for $3,995 and needed to be charged after just 30 minutes of use. Today of course the "cell phone" looks much different and it's estimated that worldwide use has grown to more than 7 billion. Phones have become ubiquitous and are carried by people in all economic tiers in all parts of the world.
