Connect titanium iphone app to an omniauth/devise rails3 app

I have a Rails3 app that authenticates using devise. We are also using omniauth, for users that prefer to log in with Facebook. I am starting to build an iPhone version of the service but am having lots of trouble authenticaing the user from the iPhone against the Rails app. Basically, I can give you a copy of the rails app, and i am looking for a new Titanium mobile iphone project that can authenticate the user to the user model in my rails app AND using facebook connect (not just login to facebook, but log in to facebook so that it also logs in to my rails app) It doesn't have to be fancy. I am ok with turning on :database_authenticatable and http_authenticable to make life easier. What you get to do the project: A zipped copy of the code to my rails app. What i expect back. The code to a working Titanium mobile iphone app that will autheniticate against my rails app in the following ways: - authenticate against my user model - authenticate using facebook and omniauth, to my rails app (NOT simply connecting to facebook, but to my rails app through facebook)
