iPhone build is a blank scene

Evening,

Just wondering if anyone has had a similar problem to this. Basically I have built a scene is unity; all is well during the preview/play mode (I even interact with it using unity remote), but as soon as I build onto iPhone I just get a blank screen (well same colour as the camera background). Now I've check my build settings, tried running with no scenes in the list (so just that scene builds) but I still have the problem. I don't think I'm doing anything no allowed by the iPhone builder, my scene consists of a ragdoll, some cubes and planes and a directional light. By the way, I've build many other scenes with this version of unity (3.30f4). It's also a pro + iPhone pro licence.

Has anyone encountered this?

Thanks.
