About time! The official Twitter app for the iPhone has been updated to include push notifications for @mentions. This means if someone mentions you in a tweet you can get instant on screen notification, once you install the update and launch the app, you are asked if you want to enable this feature.
Will you use this? Or would it just be annoying to get these kind of alerts? Remember you can of course disable this function. This update also fixes some bugs and adds some enhancements for the iPad.
