Upgrade iPad 2 from 4.3.5 to 5.1.1 I want to install iOS 5.1.1 on my iPad 2. Currently it's running on 4.3.5. iTunes just shows me a popup with the option to install iOS 6.0. How can I install 5.1.1?
There is no way to do that. Unless you already have a copy of the iOS 5.1.1 package for your iPad downloaded, you can only upgrade to the latest supported version for your device.
