[Q] Lost 4g after flashing WP 7.8
I live in the US and have a T-Mobile lumia 710. I flashed it to upgrade to WP 7.8 Ever since the maximum connection speed in the options is only 3g, and after running a speed test from the phone confirms that I'm only getting 3g speeds. Does anyone know how to fix this? I believe it may be because i used a t-mobile great britain rom which may not work on the 1700/2100 Mhz. I have thought of just trying a different Rom but I am not sure which one would work in my area. I tried to run the network setup tool, no change. I also tried to run the field test but it never loaded.
