As a smartphone user, this is one of the most annoying things: Being redirected to a cut down mobile site!
Have you ever used Google Search on your smartphone and clicked on a promising-looking result, only to end up on the mobile site’s homepage, with no idea why the page you were hoping to see vanished? This is such a common annoyance that we’ve even seen comics about it. Usually this happens because the website is not properly set up to handle requests from smartphones and sends you to its smartphone homepage—we call this a “faulty redirect”.
We’d like to spare users the frustration of landing on irrelevant pages and help webmasters fix the faulty redirects. Starting today in our English search results in the US, whenever we detect that smartphone users are redirected to a homepage instead of the the page they asked for, we may note it below the result. If you still wish to proceed to the page, you can click “Try anyway” Directing smartphone users to the page they actually wanted [googlewebmastercentral.blogspot.com]

This usually happens in cases where the mobile site does not have the equivalent mobile page and upon seeing a mobile user agent, the developer decides to redirect to mobile home page instead. What should happen in this case is to show the desktop page version.
Ideally, sure. But it also happens when the user-agent detection doesn't capture and reuse the originally requested URL, but instead bounces everyone over to the home page where they are forced to start over again. This comes up about every other week in the apache subforum ;)
