Why will iPhone not allow me to connect to wifi?
My iPhone worked perfectly for months. Recently, however, I plugged my iPhone into itunes for the first time, to download the 3.1 software and tunes to the iPod. Now, my iPhone won't connect to my wireless internet at my home or office. In fact, when I go to "settings," it says "no wifi." How do I get my phone to recognize my wireless router, as it did before?
