Google's Android update for Gmail was leaked yesterday and today sees a similar update for iOS devices. Google has released an updated Gmail for iOS app that will bring the newly redesigned inbox to iOS devices, but only if the user has already enabled the new inbox on the web.
The app update also brings with it changes to the notification system. The new app will allow you to configure notifications for each type of e-mail. This means you can stop receiving new e-mail alerts for e-mail that arrives to the promotions, social, or other e-mail boxes.
The new app is available from Apple's App Store.
