[mobile website in RoR] redirect_to issue

Hi Guys,

I'm working to show a RoR form webpage on an iPhone

WHAT I DID

1. create a model controller and view called 'form'

2. create a view for a html format and for a mobile format

3. I have the view form in the new.html.erb and new.mobile.erb file

4. for the html format I don't have problem I can fill out the form after the user push the 'submit' button appear the redirect page 'show.html.erb' and the user receive a notify mail

5. when I fill out the mobile view form from an iPhone the user receive the mail but don'y appear the show.mobile.erb page for the redirect

ISSUE

How can figure out the issue of above point 5. ? follow my form_controller.rb file

class FormsController < ApplicationController

def index    @form = Form.all      respond_to do |format|         format.html         format.mobile      end end

def new @form = Form.new end

def create @form = Form.new(params[:form])

respond_to do |format|

if @form.save

    FromMailer.notifica_email(@form).deliver     format.html { redirect_to(@form, :notice => 'ok') }     format.mobile { render :mobile => @form, :status => :created, :location => @form }

else     format.html { render :action => "new" }     format.mobile { render :mobile => @form.errors, :status => :unprocessable_entity } end

end

end

def show @form = Form.find(params[:id])

    respond_to do |format|        format.html        format.mobile     end end

end

thank you in advance
