Simon,

Thanks for your answer.

Do you have a link describing the procedure on compiling for iPhone or
is it really just ready out of the box? A description would help me
trying to do it with Android. I've done some searching, but the only
relevant hit I've found is
http://ephphatharesearch.com/Eph_Blog_Post.aspx/Show/41.

Cheers, Mikkel.
