GitHub repositories on an iPhone?

It there a way, using Working Copy/something else, to keep all of my repos on my phone, and connect computers to it?

The issue is I use 2-3 computers in different locations, and sometimes I forget to commit, then show up at a location without access To current code.

I always have my phone on me. Is there a way to keep repositories there, and connect via WebDav or sftp or something?
