Yes, of course. The last few models of the iPhone have had front cameras. They wouldn't take it out, they would improve it.

Yes, you can put an iPhone camera in an iPhone 3GS provided you have the required skills.

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.
Yes, it does.
Because the iPhone 3G was a old original iPhone that didn't have alot of things like voice control and video taking .the 3GS doesnt a front camera ethier it was envenomed when they made the 4/4s
No, Facetime is not compatible with any pre-iPhone 4 models. This is because it requires a front facing camera, and only the iPhone 4 and iPod Touch 4 have both a front facing camera and are Facetime supported.
The iphone 3gs is 2 times faster then the 3g.it has voice control you can zoom not just on the internet,a 3mp camera ,video camera,compass
Iphone 3gs has no front camera. Those are sensors, an ambient light sensor to detect the light in a room and adjust screen brightness, and another sensor to detect your face during a call to turn off the screen so you don't press buttons on a call.
Depending on what iOS you have it varies, if both iPhone 4 and 3GS had iOS5 the only difference would be not having the switch camera button in the Camera App and FaceTime.
