The official Twitter app for the iPhone has been spruced up with real-time push notifications.
This means that iPhone-owning fans of the micro-blogging phenom will be automatically notified every time someone one has mentioned their Twitter ID in a post.
Leland Rechis, product manager at Twitter mobile, wrote in a blog: "Whenever an account that you follow mentions you, you'll immediately receive a notification.
"You'll know who is talking to or about you on Twitter, and you'll be able to continue the conversation in real-time."
A future update will also add push notification for direct messages, which currently only works on Twitter for BlackBerry. Android and Windows Phone 7 updates will follow shortly.
Additionally, Twitter plans to extend the feature to text messages, so users can be notified of mentions via SMS, too.
The iPhone update is available for download right now from the iTunes Store.
