Ghettofreeryder v6 roms - Sprint, Telus, Bell

I cannot for the life of me figure out why I always get better signal with your roms. The signal is so much better that I would never want to use anything else. I have been using your kitchen (very nice, by the way) and I found if I change the carries from Telus to Sprint the signal works just like every other rom I have used. But if I use Telus then I have amazing signal.... Maybe I have been looking at this to long...Is there something different from carrier to carrier? Awsome job.....
