The Nokia 3220 was a simple device -- released in 2004 -- that quite literally lit up the lives of those who used it. While it did not have much in terms of software or features -- it had a basic camera, a 128 x 128 pixel screen, and basic messaging -- the LEDs fixed to the side of the phone would flash different colors based on different activities.
While the physical design of the phone wasn't too shocking, the key feature of the phone was a vertical strip of LEDs at the back. When a message was programmed into the phone, waving the back of the device in the air would produce letters, words and symbols spelled out in lights. It was a gimmick and nothing more; nonetheless, it was a unique selling point for the phone.
