As of late my signal has been terrible and its starting to become a nuisance. I've tried resetting my Network settings and still no luck. If I were to restore the phone as a new device, would this help or work? Also, could it be a tweak or JB app thats affecting my signal? or thats impossible? It just seems like every time I JB, my signal isn't as great as it would be if it weren't jailbroken.
