How do I update the software on my ipad1 if the "update software" option is not showing between "about" and "usage" in general settings

To update iOS levels prior to iOS 5 you need to use iTunes on a computer.

Hi Jim,

Actually I am trying to update my iPad 1 to iOS 6.x and I keep getting the message 5.1.1 is the latest?

Can I not update to 6.x on my original iPad 1?

Correct, iOS 5.1.1 is the highest possible for the 1st generation model.
