I selected an app yesterday that had to be downloaded through Wifi, so I turned on my Wifi. It shows the Wifi sign on my iPhone for about 5 seconds, then it goes back to 3G (or edge if I have 3G turned off). I have tried restarting my phone, resetting network settings, I've tried entering my Wifi password in again, nothing makes it stay connected. Anyone ever had this problem? The stupid app is just sitting there on my phone and says "loading". If anything I just want to delete the app but I can't since its not downloaded. I used to use my Wifi all the time and now all of a sudden it won't connect longer than 5 seconds.
