Thanks for the feedback. No my problem was that I didn't (/realize I had to)
set the MIME type for "mobile" in config/initializers/mime_types.rb
Mime::Type.register_alias "text/html", :mobile
That's what I was missing -- I'm sure of it cause it worked fine after I set
that correctly.
If the error message from Rails said "You didn't set a MIME type in
config/initializers/mime_types.rb for the format :mobile" that would be more
helpful. It makes perfect sense-- I just didn't realize that was a necessary
step.
