Why do I have only one AT&T signal mark after restoring to custom (NO_BB) 5.0.1 IPSW? The phone's signal seems to be fine, but the signal strength does not change at all, regardless of location. Only 1 dash.

If you preserved the baseband, you have the "cosmetic" bug referred to as the "one signal bar" bug. It happens when there is a firmware/baseband mismatch. It is cosmetic only, your device is receiving a full signal. Installing Ultrasn0w corrects the bug.
