Gmail users who rely on the Priority Inbox feature to sort their e-mail will now find the same feature available through their mobile devices.

Launched in August, Priority Inbox was designed to help clear the clutter of your inbox by filtering out e-mail deemed less important. Initially available on the standard Gmail Web site and via the Gmail Android app, the feature has just made its debut on the mobile Web version of Gmail accessible through any portable device.

Priority Inbox filters the e-mail from your regular inbox into one of three categories: Important and unread, Starred, and Everything. You start out by indicating which e-mails you consider important and which ones less so.

Over time, the feature is supposed to learn how to best sort your messages, but of course, you can steer it back in the right direction if it guesses wrong. Your regular inbox doesn't go away, so you can always access the full load of messages to make sure you don't miss any.

According to Google's blog, once you set up Priority Inbox on the standard Gmail Web site, the feature will pop up in its mobile counterpart. Specifically, Google says that Priority Inbox will work in most mobile browsers that support HTML5, including those on devices running Android 1.5 or higher and Apple's iOS3 or higher.
