It is cool that you “sniff” the end user’s device as iPhone and automatically redirect them to an iPhone friendly format of your website.
Don’t automatically redirect them to the home page.
If I’m browsing the internet on my iPhone, and click on a link to an article on … say fish … and I’m redirected to the home page because you want to show me the data in the right format, it pisses me off.
First of all, you should be happy you have a link to your site, don’t just land that user on the home page of your site. You NEED to make sure that the user ends up at the article they are looking for.
Worse than that, it shouldn’t be hard to find any specific article from the home page of the site.
