Why Can't I See The Wireless Icon On My iPhone?
With certain cellular providers there have occasionally been issues where the Wi-Fi icon will not show up even though you are connected to a wireless network. You can test to see if this is happening to you by going to Settings and turning Airplane Mode to the on position. Then click on Wi-Fi and connect to your network. One that's done, launch Safari and try to surf the web - if it's working but your phone still doesn't show the wireless icon then you should restart your phone. This usually resolves the issue.
