Apple iPhone 4S vs iPhone 3GS
Rather than the highly anticipated iPhone 5, Apple decided to be a little bit conservative and released a modified version of the iPhone 4 called iPhone 4S. This is pretty similar to when the iPhone 3G was succeeded by the iPhone 3GS; but, there are many differences between the iPhone 4S and iPhone 3GS. The main difference between the iPhone 4S and the iPhone 3GS is that the former is actually a world phone. There are currently two standard used in the world today, GSM and CDMA. The 3GS comes in either version and isn’t compatible with both. In contrast, the iPhone 4S has the hardware for both and can be used just about anywhere in the world.
Another major difference between the iPhone 4S and the iPhone 3GS is the hardware under the hood. The iPhone 3GS had a very anemic 600Mhz processor coupled with just 256MB of RAM. This pales in comparison when you consider that the iPhone 4S has twice the amount of memory and a dual core processor clocked at 1Ghz. The GPU of the iPhone 4S is also significantly better. The WiFi radio of the iPhone 4S has also been improved by a bit. While the iPhone 3GS is compatible with 802.11b/g, the iPhone 4S adds 802.11n to the mix.
Another area where the iPhone 4S shows great improvement over the iPhone 3GS is the camera. From the 3.15 megapixels of the latter, the iPhone 4S features an 8 megapixel camera; the highest sensor resolution to date of any iPhone or any Apple product for that matter. The improvement is also reflected in video recording. The 4S is able to record at a full 1080p, a significant improvement to the VGA resolution of the 3GS. And then, there is the secondary camera. The iPhone 3GS did not have any secondary camera. The iPhone 4S just carries over the VGA camera of the iPhone 4 but is still better than nothing.
There are also differences stemming from the introduction of the latest iOS operating system. But since the iPhone 3GS is also upgradeable to iOS 5, those differences are very minimal at best.

1.The iPhone 4S is a world phone while the iPhone 3GS is not
