so i got the thunderbolt a week ago and flashed the s-off and everything and got clockwork mod (coming from a dx so im pretty good at flashing roms) but now i have CM7 and it will not get a 4g signal. should i change it to cdma/evdo only or not because in the post it says not to. i may try it tommorow because in my home i ususally get 2 or 3 bars of 4g (detroit) but now there is no signal.
