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.
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.
- 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.
