Apple updates iOS 5.1

After releasing iOS 5.1 back in March, Apple has released a minor software update for the iPad, iPhone and iPod Touch. The update, iOS 5.1.1, largely addresses bugs including an AirPlay video bug that affected playback for some users. The update also resolves an issue involving an “Unable to Purchase” message that appeared when successfully purchasing an item from iTunes or the App Store. Also addressed, according to Apple, are bugs that prevented the newest iPad from switching between 2G and 3G networks and increased reliability when taking HDR photos using the camera’s lock screen shortcut. IOS 5.1.1 is a free update through iTunes or via your device’s Settings, General, Software Update tabs.
