iOS 7.1 Speeds Up iPhone 4, Still Not as Fast as iOS 6

Apple's release of iOS 7.1 on Monday included a number of improvements, but there's one demographic who should really take notice of the update: iPhone 4 owners. iOS 7.1 significantly improves the performance of the phone, although it's still not up to iOS 6 levels.

In a thorough examination of how the update runs on the iPhone 4, Ars Technica compared the launch times of several built-in apps between iOS 7.1, iOS 7.0 and iOS 6.1.3. In general, apps run noticeably faster on the iPhone 4 after updating to iOS 7.1, but there's still a significant gap when compared with iOS 6.1.3.
