I still remember my first cell phone like it was yesterday - a Nokia 5110 on the VoiceStream (now T-Mobile) network. In fact, I still have it around my home office somewhere. My first smartphone was a Blackberry Curve 8320 and it revolutionized the way I thought about communication.
What was your first mobile phone? What was your first smartphone?
