The two apps mentioned above do not require a 3Gs; if you want these kind of answers you can just search any of a million threads on the internet asking "What's your favorite iPhone app?"
cant finish reading each sentence without moving my eyes towards your avatar.. lol
very clear answer. most apps just work on all iphones its just that some are "optimized" for 3gs. graphics and performance wise.. for example camera pictures are larger. the game BLUE SKIES 3gs came out with 3gs version. another game would be DARK RAIDER 3gs optimized.
few more here and there.
