IPhone 3G and OS 4.0 Upgrade?

I have an iPhone 3G and recently received the OS 4.0 update, which is most often to the iPhone IPhone 3G and 4. I have not noticed much different, what features are available for 3G?

records and Zoom camera, thats about it. Go obsolete 3G and is not powerful enough to handle the proper characteristics.
