To be honest I don't even have the bars showing on my iPhone 4 anymore. I keep it set for the dB only. I still have perfect service even @ 104 dB. As long as your service hasn't changed and you can still make and receive clear calls I wouldn't let the number of bars you have showing bother you.

Are you on AT&T? I had the same issue—it's because you updated but preserved your old baseband. I didn't need an unlock, so I updated to 4.3.3 and allowed it to update the bb; that solved the one-bar issue. If you need an unlock, you had it right with ultrasn0w.

I did the same as massie. Also a signal of -104 is not very good. In the -70 dBm is what your looking for. It will work in the low -100s but that's at the low end of the scale. Remember these are negative numbers so the lower the number the stronger the signal. I use Signal from Cydia to keep track of tower data and signal strength.
Ah I see. I don't need an unlock since I'm on AT&T but I've kept original baseband just in case I need to sell it at some point in time to a non AT&T user. It reports very low signal regardless of what the actual signal is unless there is no service. When I am attached to my micro cell I know it should be 5 bars but it's only 1 sometimes 0 bars but service still works mostly. I get a few complaints of "I called you like 5 times already" and my phone will have only rang on the 6th call attempt.
