Somewhere in either Chicago, Baltimore or Washington, someone threw down $3,995 to buy the Motorola DynaTAC 8000X, the first handheld cellphone, on March 13, 1984 — 30 years ago today. Chairman and CEO Ed Zander jokingly introduces the 1980s-era Motorola DynaTAC 8000, the first commercially available hand-held mobile phone, during his keynote address at the Venetian during the 2007 International Consumer Electronics Show January 8, 2007. On March 6, 1983, Motorola officially unveiled the DynaTAC 8000X, but it would be seven months before the FCC gave the phone its blessing. Inside the phone, primary engineer Don Linder oversaw the development of custom integrated circuits and microprocessors — which were still a new product in the late 1970s — as well as evolving antenna designs to better penetrate buildings and account for height changes during a call, all of which had to comply to ever-changing FCC spectrum specifications. Ameritech sold 12,000 cellular phones that first year, around 10% of which were the DynaTAC 8000X.
