These are instructions on how to replace the signal strength bars on your iPhone with a numerical representation of reception strength. (ie. numbers instead of bars).

Step One
Press to launch MobilePhone from your Springboard.

Step Two
Tap the keyboard tab then dial *3001#12345#*.

Step Three
Your iPhone will now launch Field Test. Notice your strength bars have been replaced with a number. This number is your reception strength measured in decibels. The closer to 0dB the stronger your signal.

Step Four
Press and hold the Power button until the power slider appears.

Step Five
Press and hold the Home button until the Field Test program is terminated. Notice the signal strength numbers still remain.

To Switch Back to Bars
Dial *3001#12345#* again to enter Field Test mode.

Press the signal strength at the top left of screen to toggle between numbers and bars. Then press the Home button to exit Field Test mode.

Just go to settings and Erase all settings, worked for me and I had the problem some of you did not being able to JUST have bars back. I had to toggle them back in each app or screen, but even after trying Mike's advice it didnt work. Setting reset was what did it for me! Now I just have to go back a repersonalize some things which isnt too big of a deal

Still works on iOS 6.0b1! Also, to change back and forth I just has to tap on the numbers/bars.

You can REVERT THE NUMBERS BACK TO BARS by tapping on the top left corner of your screen, when you are on your HOMESCREEN (not in field test mode!). From that moment forward, you can toggle between bars and numbers straight from your iPhone\'s homescreen.
