What are the top iPhone Secret Codes

Even better, iPhone secret codes actually function. As if there wasn’t enough things awesome about this handset. Here’s a list of 7 iPhone secret codes you’ll adore:

#1: Precise Signal Strength Code

Secret iPhone Codes

When you dial *3001#12345#*, you will see a list of options. But ignore them and hold the power button until the power screen comes up, then press the home button until home screen shows again. And then, a number will be displayed instead of circles or bars on the top left. A strong signal is -40 to -80, and anything below that is bad signal, and around -140 means no signal.

#2: Hide Caller ID
