Hey, i just need some quick help. I tryed searching google, but cant find the answer. I know this is not very hard but i just cant figure it out.
I have a regular site that uses html and php, but it has to many grpahics and its a little to big to be loaded on a iphone or other mobile devices. now i want to make a simple mobile site for iphone and mobile devices and what i need help with is how to transfer a user that logs on my site thru a mobile device to my mobile site instead of a regular site?

example
http://www.vladtv.com
and when u log on thru mobile device it takes you to
http://www.vladtv.com/mobile/

how is this done? is there a simple script that does this?

Thanks in advance
