    I've managed to replace my signal strength bars by a negative number. However, I don't know how to get back to the signal strength bars.

    After reading an article, "Bugs & Fixes: iPhone 3GS signal strength oddities" in MacWorld I went into Field Test mode on my iPhone. Here is what I did:

    WARNING: Once you replace your signal strength bars you may not be able to get them back. The "more accurate numerical indicator" is much more accurate but not quite as easy to see. You've been warned.

    Quoting from the article by Ted Landau of Macworld:
    "Finally, at least for AT&T phones, you can get a more accurate numerical indicator of the iPhone’s current signal strength by manually dialing *3001#12345#* followed by a tap of the Call button."

    I did this from an original 8G iPhone. However when I got my new 3GS 32G iPhone and restored from my Mac the new "more accurate numerical indicator" feature loaded along with my data.:eek:

    If anyone knows how to restore the signal strength bars I would like to know how to do this.

    if its jailbroken you can probably disable it with sbsettings. its called numerical gsm.
    if you tap it does it go back to the graphical signal strength icon..?

    i dont have a 3gs so this is just based on using a 3g

    Did you restart the phone? Because I use that command every so often, and as soon as I press the home button, it goes back to normal. I didn't even know it was in the backup.

    Another thought: maybe try doing it again and then exiting from it the normal way. Maybe that will get it back to normal. :confused:

    How to get back to the signal strength bars revealed.

    YES! I tapped the numerical gsm and it went back to the signal strength bars.

    Thank you for the fix.
