If you’re a Gmail user on Android, chances are that you use the native Gmail app on your phone which was updated in September to bring new features like Priority Inbox. But if you prefer the web app in your mobile browser, Priority Inbox is now available there as well.
This update is more to address iPhone users who lack a native app from Google and have to access their accounts using Mobile Safari. Nevertheless, the new feature works with most HTML5 mobile browsers and that includes Android 1.5+ and iOS3+.
Oh, and if you are one of the people who uses the mobile app on Android, I would love to know your reasoning for it!
