Hi there, are you using a custom menu on your site at the moment? If so go to appearance>menu from the wp dash and use the 'custom links' area on the left hand side, half way down the page to add a url to your homepage to the menu under the label 'home'. If you're not using a custom menu currently then create one and add all the pages as well as the home link and assign it using the drop downs in the top left hand corner to the primary navigation.
Here's some more info on custom menus which can help - http://en.support.wordpress.com/menus/
The phone should connect to the site if other mobiles are, check the url again and let us know if there is any other information along with the 404 message.Go to the full post
