Where i work is right on the edge of the 3g service area and my Insipre spends all day flopping back and forth between the two, causing battery and performance issues.
I tried this but it doesn't quite work. I set it to GSM only and it forces the phone to use Edge, but only for about a minute or two. The settings stays as "GSM only" but H+ turns on anyway. Does anything else need to be changed for this to stay?
