iPhone 3G S and iPhone OS 3.0

I got my new iPhone 3GS yesterday and tested Moonlight Mahjong on the device. The 3GS has a new graphics chip, so there was some question in my mind whether everything would work right without an update. Fortunately, it works great. I can report that OpenGL graphics rendering is much faster on the 3GS, even without taking advantage of the new OpenGL 2.0 capabilities. On the new app I'm working on, I'm seeing frame rates double of what my first-generation iPhone can manage, without doing any work. Instead of 30 frames per second, on the new hardware I'm seeing 60 frames per second and above. That means very smooth animation.
