group of smartphone models produced by Apple Inc.

The iPhone 3G had been a step forward in some areas – especially in adding 3G data support – but in other areas it was no better than the original iPhone . With the iPhone 3GS, Apple took a few more steps forward with a faster processor, a better camera, video capability, and a 32 GB option.

The iPhone 3GS looks very similar to the original iPhone, but with the same plastic back as the 3G. The more efficient CPU runs nearly 50% faster than in the previous model, doubling overall performance, and it has twice as much system memory to work with. It has a 3 MP autofocus camera and supports video for the first time – albeit only 640 x 480 VGA. It was also the first iPhone with a 24-bit color display.

The 3GS was introduced in 16 GB and 32 GB versions, with the 8 GB model added in June 2010 when the iPhone 4 was introduced. The 8 GB iPhone 3GS remained in production until September 2012.
