Hold the home button and see if Siri pops up.

Almost none. Back in the 3GS days, the way to tell the difference was looking at the bottom silver lining. If it was strong and silver, it was a 3GS. If it was dull and grayish it was a 3G.

I think he means judging only on external appearance. I suppose maybe the camera lens may look different. Can't really think of anything else. If it has the 4 antenna breaks and is on AT&T, that's another way to tell.

The only way:

If it has both symmetrical antenna lines AND a sim card slot, it's a 4S.

3G to 3GS difference was on the back. Code A12 was 3G and A13 was 3GS. Didn't need to turn on the phone or whatnot.
