IPhone Applications in Python

I've been learning Obj-C, but naturally if I could use a language I already know, I could avoid a huge learning curve and get right into creating an app.
"No interpreted code may be downloaded and used in an Application except for code that is interpreted and run by Apple's Published APIs and builtin interpreter(s)… An Application may not itself install or launch other executable code by any means, including without limitation through the use of a plug-in architecture, calling other frameworks, other APIs or otherwise."
Anyway, who cares about Apple's proprietary platform? Yeah, the iPhone is cool, but if you value freedom over looks you should try OpenMoko instead. I have one of the Neos and it is pretty nice. (Not a lot of app development going on in dynamic languages, unfortunately; most everything is plain C. Yuck.)
This wording, taken at face value, means that you can't deploy a Python app. Assuming that the CPython interpreter would be the "Application" that is written using the iPhone SDK, then that Application would not be permitted to launch other executable code (i.e., your .py or .pyc files).
In fact, Sun has backpedaled on its plan to port Java to the iPhone because of this restriction: http://www.ericklein.com/2008/03/btw-i-love-apple.html
