Compare prices for Apple iPhone 3GS 16GB
The iPhone 3GS looks exactly the same as the original iPhone 3G but added some nice extras. The camera was upgraded to a 3 megapixel unit with auto focus, touch focus and support for video recording at 30 frames per second. There is also a built-in compass which neatly integrates with Google Maps, rotating the map as the iPhone faces a different direction.
iPhone OS 3.0 is installed, which added a long list of new features and software improvements over the previous version such as copy & paste, shake to undo, MMS, stereo Bluetooth, landscape keyboard, system-wide search, Wi-Fi auto-login, support for YouTube accounts and more. The battery on the 3GS improved too - already very good, it increased to 12 hours talk time, 30 hours audio playback or 10 hours video playback.
