IPhone Internet Connection
From FiOSWiki
Summary To connect to the Internet, simply use Mail, Safari, YouTube, Stocks, Maps, or Weather.
When you use any of these applications, iPhone does the following in order until connected:
Connects over the last Wi-Fi network you used that's available.
If no Wi-Fi networks you've used are available, shows a list of Wi-Fi networks in range. Tap a network and, if necessary, enter the password to join. Networks that require a password show a lock next to them.
If no Wi-Fi networks are available or you choose not to join any, iPhone connects over EDGE.
Note: You can be on a call and use Wi-Fi at the same time. EDGE is unavailable while you're on a call.
Wi-Fi
Wi-Fi is often faster than EDGE. Wi-Fi networks cover limited areas. iPhone can join AirPort and other Wi-Fi networks at home, at work, or at Wi-Fi hot spots around the world.
When iPhone is connected to a Wi-Fi network, the Wi-Fi icon in the status bar at the top of the screen shows connection strength. The more bars you see, the stronger the connection.
To see all the Wi-Fi networks in range, from the Home screen choose Settings > Wi-Fi. Tap a network to join it.
Many Wi-Fi networks can be used free of charge, and some require a fee. To join a Wi-Fi network at a hot spot where charges apply, in most cases you can open Safari to see a webpage that allows you to sign up for service.
For information about configuring Wi-Fi settings, see the "Wi-Fi" section of the iPhone User's Guide. Apple Support
