Route traffic from iphone to dektop and back

Question

Iv'e got some iOS app to pentest, and the target server is accessible only through the iPhone APN. My problem is, that i want to configure the traffic in such way so i can intercept and tamper HTTP request\responses in my desktop using burp, and route them back to iPhone:

iPhone--->Burp--->iPhone--->Server

Should i install HTTP proxy on the iPhone, or there is another way to do this? any related information will be helpful. Thanks a lot.

P.S: The iPhone is Jailbroken.

I maybe completely wrong because I don't have a phone to test it, but if your computer provided a WiFi access point, then the phone would route to it. If you tethered your computer back to your phone, I believe all tethered traffic goes over the cellular side. If that works, then you have a nice circular route without any need to be jailbroken.

Since you are jailbroken anyway, though, you can accomplish the same thing by using pf with the route-to filter to force traffic from the PC to the outside interface. Appropriately modify the commands found at http://www.openbsd.org/faq/pf/pools.html#outgoing
