    If your iDevice is using a version of iOS lower than 5, you will need to use iTunes on your syncing computer to perform the upgrade. Use the Apple link below as a guide for the upgrade.




    Also read the instructions from the section entitled "Update your device using iTunes" at the link below.

    If you have an iPad 1, the max iOS is 5.1.1. For newer iPads, the current iOS is 6.1.3. The Settings>General>Software Update only appears if you have iOS 5.0 or higher currently installed.

    How to install iOS 6



    iOS: How to update your iPhone, iPad, or iPod touch



    If you are currently running an iOS lower than 5.0, connect the iPad to the computer, open iTunes. Then select the iPad under the Devices heading on the left, click on the Summary tab and then click on Check for Update.


    Tip - If connected to your computer, you may need to disable your firewall and anitvirus software temporarily.  Then download and install the iOS update. Be sure and backup your iPad before the iOS update. After you update an iPad (except iPad 1) to iOS 6.x, the next update can be installed via wifi (i.e., not connected to your computer).


    Tip 2 - If you're updating via wifi, place your iPad close to your router to preclude getting a corrupted download.
