Q:

Resources to get started developing a dedicated mobile site

I'm going to be developing a basic site for mobile and I'm wondering if there are certain limitations/requirements/resources I should know when starting a mobile site project. 
Basically, it's going to be a simplified version of the desktop site and when the user goes to www.example.com, it will be redirected to mobile.example.com. 
Some things I would like to know:
- how to accomodate for the number of different mobile phones and their different viewport dimensions
- using javascript vs. css3
Any good resources that could help me out?
Thanks 

A:

jquery mobile http://jquerymobile.com/ is a good starting point
