    Is it possible if you go a google search? Or at least a forum search because it's been asked too many times.

    No.

    It's not possible to downgrade any iPhone's modem firmware, with the exception of the original iPhone model and a very select few iPhone 3G phones (ones manufactured very early on during the 3G model's life).
