Google on Thursday rolled out a fresh update to Gmail for iOS, infusing the experience with some much improved (and much needed) functionality. Version 4.0 is rife with new features, including the ability to directly address emails right from Notification Center; users can reply and archive messages without needing to jump into the app, making the app that much more convenient.

Additionally, Gmail 4.0 for iOS allows users to email files from other apps, and there's a handy new attachment viewer, which allows users to open attachments from Gmail into any app. It's not the most comprehensive overhaul, but it does make the app easier to use, so we're not complaining. My money is still on Microsoft's Outlook app to win this mobile email race, but Gmail isn't a bad alternative.

As always, the update is available through the iOS App Store for free.
