Up until iOS5, users who wanted to update their iOS devices had to plug it into a computer, go into iTunes, select the device, and choose the update button.

From iOS5 on, the device now lets a user update it without even using a computer. Updating is simple and should take a few minutes.

Note:
Doing the below renders the device useless until the update has finished, and can also eat up a lot of data of updating a device that uses non-WiFi networks.

To do so, follow these instructions:

1. Select SETTINGS > GENERAL > UPDATE SOFTWARE.
2. If there is an update, the device will prompt you. Just follow the screens.
3. If not, the device will display so.

That’s it.
