Apple iPhone 3GS

Although it has the exact same design, the same size (4.5 x 2.4 x 0.48 inches) and almost the same weight (135 grams vs 133 grams) as iPhone 3G, it works (launching applications and rendering web pages) much faster and consumes less energy. There is a new processor, the ARM Cortex A8, running at 600 MHz, a PowerVR SGX graphics card (hardware 3d graphics support means better 3d games) and 256MB of RAM (http://www.engadget.com/2009/06/19/iphone-3g-s-gets-the-quick-and-dirty-tear-apart-treatment-alrea/).
The battery life is extended to 12 hours of talk time on 2G and 5 on 3G, with a up to 300 hour standby time. On the other hand you will get 5 hours of internet use (3G), 9 hours on wi-fi internet, 50 hours of audio and 10 hours of video playback.
Although it supports (as its predecessor) three band UMTS/HSDPA, four band GSM/EDGE, Wi-Fi 802.11b/g and Bluetooth 2.1 + EDR, it is also supports the 7.2Mbps 3G standard, which means that you will get data faster to your iPhone. As you probably know the “S” stands for Speed, and there are some benchmarks against competitors (http://www.engadget.com/2009/06/20/iphone-3g-s-and-pre-head-to-head-benchmarks-iphone-barely-wins/) that confirms it almost clearly.
In addition, there is a new camera, with increased resolution to 3 megapixels, autofocus, auto exposure and auto white balance — and just as expected, now supports 30fps VGA video recording with editing features. You will find also special macro and low light modes, and photo&video geotagging functionality.
Closing let’s talk about new features, such as the Magnetometer, which works with a Compass application, third parties, and it is integrated into the new Google maps app, showing your orientation with a small semitransparent cone. In addition, you will get voice control functionality which means that you can call people just saying their names and some accessibility features, like zooming on text, inverting video, and voice over when you touch whatever text is on screen.
