Hello Kris, It seems similar to https://bugzilla.xamarin.com/show_bug.cgi?id=7664 (even if the original description is private). Still you can c.c. yourself to the bug report to get updates.
I can evaluate the trust correctly from MonoTouch itself, but not from the WebClient (and the results should be identical). So there's a bug hidden in there (and I'm looking into it).
