Yes, the iPhone 3G/3GS is thicker than the iPhone (first generation) at its thickest point. The iPhone 3G/3GS is 12.3mm while the iPhone (first generation) is 11.6mm. However, the iPhone 3G/3GS has a tapered back, and has roughly the same overall volume as its predecessor.

yes, but not all iphone 4 apps are available on the iphone 3gs/3g/2g becuase they are too high resolution apps, or need a front facing camera.
