The iPhone does not have a conventional redial button on the phone keypad. Nevertheless, you can easily recall phone numbers that have already been dialed. That's how it's done.

If you really only want to access the last number dialed, proceed as follows. There is a green button with a handset on the »numeric keypad« in the iPhone's phone app. Typically, you use this to connect after typing a phone number. If you leave the field for the number empty and press the handset button, the last number dialed is automatically entered. A second click on the green button selects them.
