Wow, what a stupid answer...To contribute to your thread, my favorite iPhone 3G game at the moment is Field Runners. It's not free, but I love it.
My favourite time killer is Scoops. Passes the time really well and never gets tiring.My favourite thinker would have to be Fuzzle. Not really a thinker per say, but you do have to use your head a little bit and it goes real quick.My favourite free game would be Knots, gets challenging as you go on.
