A few minutes ago Apple released iOS 5.1.1 for iPhone, iPad and iPod Touch, I explained it here some useful information and now I list only the links for the direct download of the new version of the operating system:
- iPhone 3GS
- iPhone 4
- iPhone 4S
- iPod Touch 3G;
- iPod Touch 4G;
- iPad
- iPad 2 Wi-Fi
- ipad 2gsm
- iPad 2 2012 Wi-Fi Only;
- iPad 3 Wi-Fi;
- iPad 3 (GSM)
If you don't want to install iOS 5.1.1 through iTunes, then you can do the OTA Update directly from your iDevices by accessing the menu: Settings>General>Software Update. iOS 5.1.1 has 189 MB via OTA Update, but you must be connected to a Wi-Fi network to be able to apply it.
