Can you use a bluetooth mouse with an iPad?

I'm pretty shocked there isn't an app that's been developed that would allow you to control a pointer via a bluetooth mouse. Even if the pointer is part of the app, designed to simulate a finger hitting the screen.

I'd like to do this also without having to resort to a jb.

Proves it's possible. Too bad it requires a jb.
