Well I upgraded to IOS4 from 3.1 on my Iphone 3G last night, and my reception now is terrible. Before, I used to have full bars almost 95% of the time. I only lost reception in the subway, or in my concrete fortress of a college. Now on 4.1, I am sitting here on the main floor of my house, having 3 bars. I rarely get full bars, but once I do, it just goes right back down to 3, sometimes reaching 1 bar. 3 Bars seems to be where its hovering at. Is this a problem, or have I always had the same reception, but the IOS4 is just better at telling how much reception I have.
