Apple updates iOS to version 5.1.1

Apple has released an update to its iOS mobile operating system, version 5.1.1, which it claims removes some bugs and improves reliability of some options, but which does not address the wireless connectivity problems - well, at least not overtly, The Register reports.

The update, released Monday, is for the iPhone 3GS and later, the third- and fourth-generation iPod touch, and the iPad and iPad 2 - presumably by "iPad", Apple means both the original iPad and the third-generation iPad, aka "The new iPad".

According to NDTV, the update improves reliability of using the 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; improves reliability for syncing Safari bookmarks and Reading List; and fixes an issue where 'Unable to purchase' alert could be displayed after successful purchase.

The updated software can be downloaded from Apple.com, via iTunes, or over-the-air on compatible iDevices, Hindustan Times notes.

Alternatively, writes IT Business, users can install the update directly from their iOS devices, if they're running iOS 5 or later: Launch Settings, tap General, and then tap Software Update. As a delta update, the iOS 5.1.1 upgrade is a much smaller file than iOS updates before iOS 5 generally were.
