There are a number of ways to view your WAPL on a mobile device.
On a mobile
The easiest way is to get out your mobile and browse to the URL of your application!
Firefox add-ons
You can install a couple of firefox add-ons that will help you develop your application.
- WML Browser
- XHTML Mobile Profile
- User Agent Switcher
Once installed, firefox will then act as a mobile (which one depends on which user agent you install!) and will be detected correctly!
