The iPhone 3GS is the third iPhone model released by Apple. It takes the second-generation iPhone 3G as its base and adds fine-tunings and a few major new features.
The major changes to the iPhone 3GS come in the areas of performance and media. The 3G S performs much faster than the 3G, with Apple claiming an overall two-fold increase in speed.
In the media arena, the iPhone 3GS sports a new camera that boasts 3 megapixel and can record video. The phone also includes onboard video-editing software. The iPhone 3GS improves in battery life, also, when compared to the one used in the iPhone 3G.
The iPhone 3GS doubles the capacity of the iPhone 3G, offering 16GB and 32GB.
As with both previous models, the iPhone 3GS has a 3.5-inch touchscreen and runs Mac OS X.
