Were I afforded only a tweet-sized 140 characters to share this news, I might say it as follows:
Twitter’s updated, innovative iOS app now supports push notifications for mentions and DMs, simplifies geotagging, and improves the UI lots.
My editors don’t enforce Twitter’s draconian character limits, though. So I can explain further. The updated version of Twitter’s free, official, universal iOS app includes both new features and marked improvements.
On the iPhone side, the Twitter app now offers push notifications when someone replies to you or sends you a direct message. The push notifications are clearly in their infancy, though—they appear to lack the nuance of a service like Boxcar, which lets you specify “quiet times” when you’d prefer not to receive alerts at all. The iPhone version also improves the display of shortened URLs, lets you enable geotagging with a single tap, and handles iTunes Store links better.
The iPad version of the Twitter app now offers better support for inline media (such as images and videos), lets you manage your saved searches, and offers what the company calls “UI improvements.” The two most notable of those UI improvements correct serious annoyances of the app’s iPad interface: selected tweets no longer get pinned to the bottom of your timeline, and it's now much easier to clean up the screen after you’ve drilled down through several links.
Twitter requires iOS 3.1 or later.
