Software Malfunctions Caused by ZiPhone

I've received a couple broken iPhones recently that have the exact same, and currently unsolvable, problem: Invalid calibration data in device tree. In neither case was the owner of the iPhone aware of this situation. So I'd like to put out some information on this problem so that you can determine whether or not you have this issue. In short if your phone seems to work fine, then don't worry about this. These symptoms are quite obvious, and dire.

- If you DFU restore the iPhone, iTunes will give you a 1011 error. This indicates a mismatch between the baseband and the firmware on the iPhone. This should NEVER happen during a restore so this is a definitve sign.
- Repair needed message is displayed.
- If you press the "i" button from an unactivated iPhone it will display the IMEI and ICCID as "unknown".
- No carrier signal bars
- In your Settings screen, the Wi-Fi will be greyed out and say "No Wi-Fi".
- In your General screen, the Bluetooth will be greyed out and say "Unavailable".
- In your About screen the Wi-Fi Address will say "N/A", and the Bluetooth address will say "00:00:00:00:00:00", and the IMEI, ICCID and Modem Firmware will be blank.
- There is no sound.
- If you go into Field Test mode, the Firware version will be blank.
- The iPhone will take a long time to turn on and shut down.
- Of all the reports I've read, there has been one common factor: the use of the ZiPhone program.
