My new VZ iPhone has worked great since I got it on Monday. Now all of a sudden last night it would be on 3G instead of my home WIFI. I reset wirelesss, even restored the phone. The crazy thing, if I go into settings > network, it will turn on, but it is only on while I am in that section fo the settings menu. As soon as I leave and go to the home screen it goes back to 3G. Any takers?
