If a mobile user goes to a 'deep' link on the website (i.e. www.example.com/some-path) and is redirected to the mobile site, they get sent to the root URL (i.e. http://m.example.com), losing the path information.
The rewrite rules specified here https://github.com/browsermedia/bcms_mobile/wiki/Configuring-Apache should be updated to keep the path informaiton
