25 years of commercial mobile phone use in the USA

Today, 13th October, is the 25th anniversary of the first commercial mobile phone call in the USA. (Well, on a cellular network, anyway). Back in 1983, the president of Ameritech Mobile Communications called the grandson of Alexander Graham Bell in Germany using a Motorola DynaTAC 8000X. Incidentally, the first-ever public mobile phone call was made in April 1973... and the UK's first commercial call was in January 1985. [CTIA press release]
