I thought it might be a good idea if we started a list of all the problems that people are having with the iPhone 4. This is not a thread about if you don't have problems or you truly believe that aren't any issues. Proximity Sensor not registering correctly Camera lenses not opening or closing SIM cards not registering Phone Antenna signals Swapped Volume Control button Possibly shocking people Screen Positioning iPod app crashing Bluetooth disconnecting Wi-Fi Antenna issues Yellow spotting - Should resolve itself after few days though. This is all that I know of currently. If you are having issues please post here so that they may be added to the list.
