It has come to my attention the nubmer of people who do not know how to do a proper mobile redirection.
When I saw Philip's comment in this thread: How to determine if a visitor is using a phone or computer I decided I needed to share my knowledge on the matter.
You can absolutely (Im correcting Philips answer here) redirect mobile browsers 99.27% of the time using a simple php script placed at the top of your index page.
I use the script from: http://detectmobilebrowsers.mobi/
I've used it for about a year now, and as long as you update the WAP list, then the % of mobile browsers redirected to the mobile site sucessfully will increase.
If anyone has any questions about this post it below.
