Apple has released the new version of it’s mobile OS, so if your device matches the requirements (iPhone 3GS and up or iPad 2 and up) you can have it in a matter of … hours because the download speed is currently pretty slow. But still, we’re excited for the new features, especially Passbook which will create a completely new service for designers! Great stuff.
In case you don’t know how to update – go to Settings / General / Software update on your iOS 5.1 device.
