cannot get RewriteRule for just the document root to work

[Lance Campbell <lance@xxxxxxxxxxxx>]

Assume my site is: acme.com

The following redirects and works as expected:

RewriteCond %{HTTP_USER_AGENT} iPhone.* 
RewriteRule ^/index.html   http://test.webservices.illinois.edu/mobile.html [R,L]

So if I go to http://acme.com/index.html it redirects me to the mobile.html page.

BUT if I go to http://acme.com/ it does not redirect me.

So I thought the following would work but it does NOT:

RewriteCond %{HTTP_USER_AGENT} iPhone.* 
RewriteRule ^/   http://test.webservices.illinois.edu/mobile.html [R,L]

How do I get just the base root to redirect?  I do not want other pages within the site to redirect.

So http://acme.com/abc.html would NOT redirect.
