Mobile Site Redirect
 

I have finally got around to sorting out our mobile site utilizing the ElevatedX mobile plugin and I'm pretty happy so far.
I have questions about home page redirects for those in the know.

OK, bare with me while I try and explain this.
Our original home page was www.kinkykicks.net/index.html which meant that search engines list us in the desired format of simply www.kinkykicks.net (ie no index.html).
Now to enable mobile traffic to redirect to mobile.kinkykicks.net I have replaced index.html with index.php which is a sniffer script provided by ElevatedX. This directs standard traffic to /home.html and mobile traffic to the mobile subdomain.
I have included the original header / meta information in the index.php redirection script and I have also cloned the original index.html information into home.html.

So my question is: will these changes affect how search engines find us? I have got top page lists from google searches now and am worried these changes could affect this.
In light of the above changes will search engines still list us as www.kinkykicks.net even though the index page is a redirection script?
One of my concerns for /home.html coming up top in web searches is a) it doesn't look as clean to me, but b) the mobile redirection script is completely bypassed.

Or is there a better way to go about this? I've looked at other sites (including this one!) with redirects from the home page but cannot see how this is accomplished from page source information.

Any constructive advise is muchly appreciated.
