I was interested in making a mobile version of my site. I had stared to see more and more sites that were made with a mobile version.
As I use wordpress for my site i started to look at what plugins were available.
WPtouch seemed to offer what i was after. It is a simple plugin that defaults the site to a mobile version if it detects it is on a mobile phone.
The main things to do are to upload an image so that it can be saved to the hompage and select which pages to include.
It is really simple to set up and makes it very easy to create a mobile site.
