Got my copy of Uncharted 2: Among Thieves at the moment, been playing it for days. This is a must have for all PlayStation 3 owners, I have never seen such a sharp and rich graphic on PS3, much better than my favorite game Resident Evil 5. If you got 10000 points in the game, you can unlock a bonus movie titled Mastering the Cell Processor to tell you how they achieve such a great graphic, finally they use a lot SPU to do various stuff!
These days I’m working on a better implementation of AI for my game Gomoku, and found that when performing pure math & logic calculations, iPhone simulator is vastly faster than real device, maybe 10x times! I implemented a new way to calculate next move for computer in the board name, it took few seconds to calculate inside simulator, but more than 30 seconds on real device. Interesting. I need to put more work on my algorithm, definitely!
If you’re going to create your own iPhone games, with help from a good game engine, your life will be much easier, and you’ll be able to focus on executing your ideas, not the low-level details involving too much math and OpenGL.

Unity iPhone
Unity is a commercial iPhone game development environment, it has got everything you’ll need for developing a 3D game. The only problem is the licensing price is too high, the combination of Unity Pro and iPhone Advanced could cost you $1499 + $1499. It’s quite a lot.
