How do I set up Wi-Fi on my iPhone? | iPhone Questions

Open the phone’s setting area and select Wi-Fi. The phone will then search for available Wi-Fi networks.  When you see the network you want to connect select it and tap ‘Join’.  You will then be asked for the password. Once you enter the password you phone will then connect to that network.
You can then open the MailOnline iPhone app and sync quickly using your Wi-Fi connection. Once synced you will be able to enjoy the app offline anytime, anywhere.
