Apple has restored the ability to test the quality of your phone’s signal reception when it released iOS 4.1. The feature was omitted from Apple devices after the whole “Antennagate” scandal regarding poor signal reception when holding the iPhone 4 a certain way.

The iPhone 4 consists of two antennas, both are stainless steel bands that run around the base of the phone. One is for cellular voice and data, and the other band is for Wi-Fi, GPS, and Bluetooth service.
When those two bands were connected via user’s conductive finger tips, signal strength dropped significantly. After this malfunction was noticed by the masses, Apple nixed Field Test mode from the operating system. But Apple finally reinstated the ability.
Users can access Field Test mode on any iPhone running 4.1 by calling *3001#12345#*. Once called, the Field Test window will open and the iPhone’s signal bars will be replaced with a precise decibel readout. To exit the window, just press the Home button.
The lower the number the better; a typical measurement should look like “-92″. When iWinUX asked our readers what kind of readout our users were receiving, we got answers ranging from -95 to -9000.
