redirection and ranking

[limoshawn]

I have www.example.com which was ranking well for terms related to the site. A few months back i decided to give mobile users some content. i changed the home page to include a php script to determine if the browser is a mobile device or a regular pc and then redirect appropriately.
so now when a user comes to www.example.com they are redirected to either www.example.com/main.htm or www.example.com/mobile.htm based on the users browser.

By doing this, have i killed the ranking of www.example.com since it no longer has any content?

Is there a better way to accomplish what i'm trying to do here?

I would have to say yes you have.

The mobi domain is used just for this so I suggest u buy the mobi domain and build it for them and take that script out of the site.
