Twitter has updated its official application for the iPhone to version 3.0.1 to support the newly-released iOS 4. According to the release notes, the new version of the Twitter for iPhone has been enhanced with OAuth for more security when posting tweets, photos, or videos. Additionally, the new version of the app includes support for multitasking and the new iPhone 4 Retina Display along with a few other bug fixes.
Twitter for iPhone is one of the first applications to support the new iOS 4. Facebook recently released an updated version of its iPhone application. Unfortunately, the Facebook update did not include support for the many features found on iOS 4.
You can download the new Twitter for iPhone application directly from the iTunes App Store. Be sure to let us know what you think of the new Twitter for iPhone application.
