Simple code gives access to iPhone’s secret

A SIMPLE code can give you access to hidden information your iPhone, as well as allowing you to make changes to its private settings.

The iPhone's Field Mode is a largely hidden but useful tool that allows you to see extra information about how your phone is connected to the internet.

The tool is enabled by dialling *3001#12345#* and then pressing the call button. Your phone will switch away onto a grey screen, after which you'll see the extra information.

One of the most useful features is a more detailed signal strength indicator which should appear in the top-left hand corner.

Anything above -80 is roughly equivalent with full bars on the normal scale. Anything below -110 would be one or no bars and you are unlikely to be able to easily make a phone call.

In practise, the maximum strength ever achieved is around -40. No reception at all is around -120, though it goes all the way to -140.
