My name is in the credits for Python for iOS as I provided the pure python patches for urllib to even work in the first place :)
There is also a link in the credits next to my name for my github repo which contains the original patches, plus some new code I just uploaded (shpy - a pure python shell-alike, with bash-like file name globbing and file download + unzip)

I also was involved in working with the requests/urllib3 maintainers to get these modules working in Python for iOS, as it didn't originally ship with ssl support.
My original patches could self-install with a simple one-liner copy&paste, which then gave you the '_rp' module (now included in the app).
I will add a similar one-liner for the installation of shpy (and better documentation) but should you get it installed, operation is as follows:
from shpy import *
shpy()
Currently there is a bug with raw_input where the prompt is printing after text has been entered, so I'm working around that right now.
I also plan on adding untar support, PyPI pure python module installation, and WebDAV.
If you have questions, let me know.
