How to Get Free WiFi for Your iPhone
The iPhone is a line of mobile phones designed and produced by Apple. In addition to the cellular handset, which is used for voice calls, the iPhone comes with built-in network interfaces to accommodate data traffic over Wi-Fi, Bluetooth and 3G cellular protocols. A connection over Wi-Fi typically provides the fastest access to the Internet. Wi-Fi has the advantage of not being metered by the mobile service provider, so no access quotas apply. Free Wi-Fi networks are widely available at coffeehouses, libraries and some places of business. Connecting your iPhone to a free Wi-Fi network is straightforward and takes only a few minutes.
Press the "Home" button on the iPhone. Slide your finger across the screen to unlock the touch-screen.
Tap "Settings" and then "Wi-Fi." The iPhone's operating system will display a list of all wireless networks within range.
Look down the list and find a free Wi-Fi network that you'd like to access.
Tap on the entry for the network that you want to join. If the network is secure, the iPhone will prompt you for a passcode. Obtain the passcode from the network operator if you don't already have it. Type the passcode and then tap "Connect." The iPhone will log in to the free Wi-Fi network.
