[iOS] Any recommendations for collision/physics engines

[simedj]

I know it's not Ogre strictly speaking but I know some libraries are widely used in Ogre, however I don't know which support iOS well.

Has anyone here integrated a collision detection library to an Ogre iOS project? So far I found bullet claims iOS support but any recommendations? Something that could be build & used fairly easily is preferred - i.e having an iOS build out of the box would be perfect.

Thanks!
