Mobile Rails Development


I want to develop a Rails application for a mobile device. Would
anyone know of any tutorials on the web on how to create a mobile
application view using Rails?


Assuming you mean "a web app people access from their mobile device" then the main issue is making sure your views are all appropriate to the accessing devices. This may mean complicated logic to display the correct view for each different device.

If you mean an app that runs natively on the phones then I believe you're blazing new ground -- you might look at whether you can deploy an app using JRuby and J2ME.
