iphone 3g vs 3gs which one is better?

Speeding: the iPhone 3G than the previous model, was increased in the current CPU speed, particularly in the launch applications, open web pages and upload attachments.There was a significant improvement even in the games section, with a better view.

Camera: starting from this model of the iPhone, is an integrated 3 megapixel camera that can also record videos, take pictures as well of course. The camera has autofocus and a feature that focuses on the part of the picture you want. The videos, IOS4 through, you can cut, assemble, store them on the Mac and PC, and share them on YouTube or MobileMe (the latter function, by e-mail or via bluetooth). The videos can then be turned in either portrait or landscape.

Voice Control: just press the home button three times to "call" voice control. Pronouncements should be the name (or artist) to listen to a song, or say a name in the directory if you want to call.

Digital compass: always from this model, the iPhone is also able to show the way to go: the application can be used individually or together with maps, maps to guide the direction you're holding the iPhone .

Nike + iPod: The iPhone 3G also includes the Nike + iPod support.

IM and Vodafone have offered for sale at a price of 619 € for the 16GBmodel and 719 € for the 32GB model.

From above, I would like to recommend you iPhone 3GS.
