    Since installing 3.1.2 my iPhone 3GS gets 4-5 bars on 3G in my Apartment, versus 0-1 before the update. If I deactivate 3G, I still get 0-1 bars.

    It seems like my signal strength is better all over the Apartment when 3G is active. Did the update improve 3G signal strength for anyone else?

    I checked the signal strength in Field Test mode, and it fluctuates between -90 and -100 when connected to 3G depending on where I am in the Apartment. With 3G deactivated, it's more like -100 to -110, if it can connect at all. Should this difference manifest as "full strength" versus "no service"? Has reception really improved, or did the 3.1.2 update and/or Carrier File 5.6 make the iPhone display reception as superior to what it really is?

    Anyone else see something similar? Did they put up a new tower in my neighborhood or something? (can't confirm that immediately after installing the update reception changed...could be a coincidence)

    not for me. Prior to the update, my signal was -75, and it hasn't changed since the new update.
