Get inside the iPhone with the field test mode

In case you are a curious cat and always wanted to know the inside system of the iPhone, there is only one thing you can do which is going into field test mode.

To get in the special mode just dial *3001#12345#* and hit Call - the next menu you will see is the main screen of the field test mode (image on the right). This screen displays the following options: Network Information, Cell Information, GPRS Information, PDP information, Call Information and Versions.

If you keep digging the menus you will have access to some information such as: received signal strength if you are in a call, details of the cell phone towers that the iPhone can currently see, details of the call that you are currently in, and ID of the LCD panel.

Check more details of the iPhone field test mode at WirelessInfo.

PS - MobileWhack cannot be held responsible if you somehow "damage" the iPhone.
