Twitter has released an update to its official iOS application with a completely redesigned user interface for iPad users. Departing from the prior unique sliding panels interface, the new iPad version now uses a full-screen UI adapted from the iPhone and iPod touch, with the standard navigation buttons on the left side and a single timeline view. The new layout makes use of the additional iPad screen space by providing header photos in user profiles and photo streams on profiles and events, however it does not expand when using the iPad in landscape orientation, leaving empty space to the left and right of the timeline view. The iPhone and iPod touch user interface remains the same in this update other than minor improvements, polish and fixes. Twitter 5.0 is a universal app requiring iOS 5.0 or later and is available from the App Store as a free download.
