Titanium iphone with Facebook connect to rails devise app

I'm developing an iPhone app with Titanium which is doing API calls to a Rails3 app with Devise/Omniauth.

And I just can't seem to get how to FB Connect in the app and then be able to auth my API calls. There's is a start here but it means that the user has to:

1. FB Connect in the app
2. Send the result to the rails app to get a devise token
3. Ask for what it needs to using that token

Is there any way to directly use the result of Step 1 an开发者_开发问答d get rid of Step 2?

Super thanks!

you can make the facebook connect calls directly from the titanium application.
