Apple just pushed out an update to iOS 5.1.1, which brings with it a handful of bug fixes. The update is available to download either through iTunes or through the the Software Update tool in your iOS device's Settings menu. iOS 5.1.1 is available to the iPhone 3GS, iPhone 4, iPhone 4S, iPad, iPad 2, new iPad and both the third and fourth-gen iPod touch. Here's the full changelog:

• Improves reliability of using HDR option for photos taken using the Lock Screen shortcut
• Addresses bugs that could prevent the new iPad from switching between 2G and 3G networks
• Fixes bugs that affected AirPlay video playback in some circumstances
• Improved reliability for syncing Safari bookmarks and Reading List
• Fixes and issue where 'Unable to purchase' alert could be displayed after successful purchase

While this looks to be a fairly minor update, the last time that Apple pushed out an update was for iOS 5.1 back at the beginning of March, so I'm sure that iOS device owners are happy to see iOS 5.1.1 arrive, giving them the chance to bask in that new software glow. If you've got one of the compatible iPhones, iPads or iPod touches, you can plug it into your computer and fire up iTunes or head into Settings > General > Software Update on your device to see if iOS 5.1.1 has made its way to your neck of the woods. Remember to give us a shout once you get it installed!
