My first cell phone was a Motorola car phone somewhere around 1987. It cost me $900, installed. I do not remember the brand/model of my first hand-held, somewhere around '89. Since then:
Motorola DPC 500 (the original flip phone)
Mitsubishi 3000 (?) - at the time, the world's smallest & lightest cell phone. I remember paying $720 for it in the early '90's.
Motorola Ultra Tac
Some Nokia
Another Motorola (model unknown). It died due to water damage received while covering Hurricane Charlie in 2004, Since then, only MIL-STD 810F, water resistant Nextel Motorola phones.
Nextel Motorola i305
Nextel Motorola i355
Sprint-Nextel Motorola i1
There were probably others that I have forgotten about in-between my first hand-held and the i305.
