    Does anyone know how to put the 650 phone into test mode to observe the channels or frequencies being used? All phones have a test mode that allows a tech to monitor performance. I'm testing an in-building signal booster and I need to determine which band(s) are really being used in my area.

    For verizon ... pull up the dial pad, dial: #*#33284# press dial. Other carriers have same thing but some variation without * i think. By the way 33284 spells out DEBUG. Good luck.

    Thanks. I should note that I need the Cingular code and any key to what I'll be looking at might be useful.

    GSM, no, unfortunately does not exist. If someone has information otherwise, feel free to speak up.

    RSSI for Unlocked GSM is #*744625. I dunno if it works with any GSM or just unlocked.
