Phantom Fish let us know that its ByLine RSS reader app has been updated to version 3.2, adding features that take advantage of some the new capabilities of iOS 4. Most notably, the app can now continue synchronization and caching activities in the background, allowing users to go to other apps while these tasks are completed. Additionally, high-resolution graphics are now included and will be implemented accordingly on the iPhone 4 with its 326 ppi screen.
iOS 4 was just released yesterday and compatible apps started appearing in the App Store last week. With the release of the iPhone 4 this week, we expect an avalanche of app updates featuring optimizations for iOS 4 and the iPhone 4′s Retina Display, internal gyroscope, and other hardware improvements over previous iPhone models.
