Google's Priority Inbox feature is now supported in the Gmail Mobile web app
. Priority Inbox automatically sorts your incoming email and pushes your most important messages to the top of the page, and it was previously only available to desktop users and those running the Gmail app for Android. Now, anyone with an HTML5-friendly mobile browser -- including Android 1.5+ or iOS 3.0+ users -- can take advantage of the feature.
You'll still have to set up Priority Inbox
from the desktop version of Gmail, but once you do it will start working automatically on your mobile device. Important emails will appear under the "Priority Inbox" label, and yellow "importance marker" flags will show up next to important messages in your inbox.
