If you want your mobile users to access your sharepoint site, here is the solution
1. Add the following parameter (?Mobile=1) to the URL of your existing Sharepoint site homepage
For example, http://[yoursite]/Pages/default.aspx?Mobile=1
This is the standard mobile page view.
Going forward, you need to be able to direct mobile users to the mobile version of your site.
To do this you would need to either redirect mobile users to the ‘mobile URL’ or add a link to the ‘mobile URL’ on your homepage.
