Phantom Fish has released an iOS 4 update to its popular Byline RSS client for Google Reader. Byline 3.2 introduces higher-resolution graphics for the iPhone 4 Retina display and adds background task completion for multitasking-capable iOS 4 devices. When exiting Byline on an iPhone 4, iPhone 3GS or third-generation iPod touch with iOS 4, the app will finish the current syncing or caching process in the background. Fast App Switching is also supported on these devices to allow users to quickly return to where they left off when re-entering the application. Byline 3.2 also tweaks swipe sensitivity to improve navigation and fixes several bugs related to syncing, caching and handling of links to iTunes and the App Store. Byline is available from the App Store for $5 and is a free update for existing users. A free ad-supported version is also available.
