iPhone 3G S includes a 3 megapixel digital camera that can also record video at 30 fps though there’s no flash. You can also edit your recorded video on the iPhone 3G S itself by trimming the non-essential parts from the video and then upload it to YouTube.

The size of the iPhone 3G S is the same as the old iPhone 3G but it includes a better processer and more RAM so it’s faster and more responsive than the old iPhone. The built-in Safari web browser can also render web pages more quickly now.

The most interesting difference is however battery life. Apple says the iPhone 3G S battery life can be as high as 9 hours for Internet use over Wi-Fi which in the case of iPhone 3G was about 5 hours.

And when it comes to price, iPhone 3GS is almost double the price of iPhone 3G but we don’t know if Apple will extend that benefit to iPhone customers in India.
