The N-Gage QD is a handheld game console and smartphone by Nokia, and a redesign of the N-Gage. It was unveiled on April 14, 2004, and was released on May 26, 2004, running the same Symbian OS v6.1 with Series 60 1st Edition FP1.
It revised the original N-Gage's physical design, being smaller and rounder. It corrected the flaw of the original's cartridge slot placement with a more convenient one on the bottom of the device as opposed to behind the battery. This design also moved the earpiece to the face of the device, rather than on the side, as in the previous model.
The device retailed at a lower price compared to the original N-Gage device, aided by the fact that it was usually sold with service contracts and applicable subsidies. For instance, in the United States the N-Gage QD was available as a prepaid phone offered by Cingular at retail games stores such as Electronics Boutique and GameStop.
