Is PhysX being used on mobile

When the doc http://unity3d.com/support/documentation/Manual/Physics.html mentions PhysX, does that also apply to mobile as well? PhysX is an NVIDIA technology, and many mobile phones are not using NVIDA chips, so I am wondering if that’s desktop-only.

PhysX is software-only on all platforms, and the graphics chip is irrelevant concerning physics. PhysX isn’t really nVidia technology, at least not originally; it was created by Ageia and only bought by nVidia relatively recently.
