Developing a Mobile Website
Aug

480x320 is a very popular size if your primarily target is the newer smartphones. I recommend using simple HTML and avoid Flash and other multimedia contents. iPhones are not compatible Flash by Adobe.
Also, tablet devices like iPad, iPad2 and Android Pads can display as much as PCs, so having the option to switch between mobile website and regular site is a very good idea.
PSPINC, web site hosting service provides you (developers) with the way to recognize the mobile devices and redirect the user to the specific directory so that you can automatically display regular or mobile version of the website.
