Few questions Iphone and car example or books?

[Mars_999]

I been using PhysX, I know, I know, but now I am thinking about switching to Bullet, but I need to be cross platform, PC/Mac/Linux/iPhone. So from the looks of it Bullet is on all those platforms, and I am guessing its the same license for all them?

I would like to buy a book if possible, but a good tutorial or example is needed so I can get a grasp on the whole SDK. Any suggestions?

I am specifically looking to setup a car model with 4 wheels. I don't need super accurate, but I need it to be able to do collision detection against a road/track and some simple objects e.g. cube/coins ect....

Any feedback would be greatly appreciated.

Thanks
