Depends on your current version, for iOS 5 you can just go into settings -> general -> software update and do it.

With older versions like iOS 4 though you'll need to connect to a computer using a usb connection, and then update using iTunes (on that computer). NOTE: if you are updating from iOS 4 you should sync with the iTunes first otherwise you could overwrite all your app, music and other info.

Hope that helps.
