    Looking through it you actually have values called rx and tx power (in dbm). not sure what the difference between those and rssi value is.
    The difference between dB and dBm is really pretty simple. You already said what the difference was you just might not have realized the units that you were speaking of.

    RSSI is a unitless number that is expressed as a ratio, thus the dB logarithmic scale. If I were a betting man the RSSI value that is shown on this screen would be a ratio of the received power versus the transmitted power in logarithmic scale. So basically RSSI is a multiplication factor that relates two numbers.

    dBm however is the exact opposite, it is a unit based value. It directly relates to a measurable value specifically mW (milli-watts). 0 dBm = 1 mW. So as an example mine was showing -76 dBm which is equivalent to 2.5e-8 mW.

    Sorry if you didn't really want to know; I just wanted to be able to help where I could since nothing else on these forums I can really contribute to. BTW I have a degree in Electrical Engineering and am an RF engineer so I kind of know what I'm talking about; only kind of though.

    isnt the MSL number tied to the ESN? I could have sworn there are converters out there i used under winmo which would pull it from the ESN HEX value.

    no... msl is not computed from the esn... there are programs that can read those values from most cdma phones... both values are changeable using the right software, although it is illegal to change the esn. you may be thinking of the akey which can be computed...

    That's AWESOME! I wish they had this information available in the main O/S. Sort of just showing you a blip on a map, I couldn't find anywhere that listed the LAT/LON, altitude, direction and speed!

    Thanks!

    Is there a comprehensive list of these codes somewhere? I know they may not all work on the Pre, but its worth a shot.

    Here is a list I pulled off everythingtreo.com

    Code:
    #*#377#. Ever wondered if there was more to this than just showing the system error log? That’s the Verizon variant of the error log code, which is one of the many (and often times mysterious) hash codes that give you access to hidden features on your Palm device.
    
    Please note: The function of some of these codes still remain a mystery to enthusiasts. A lot of them were discovered through trial and error (yes, we have a lot of time on our hands), and while the presence of some of these codes can be easily discovered this way, their purposes are often more difficult to understand. We have indicated some codes with which users should be particularly careful. Also, these codes have only been tested on Palm OS devices, so we cannot confirm nor deny their usability on Windows Mobile devices.
    
    There are three parts to a hash code - the prefix, the code, and then the suffix.
    
    1. The Prefix
    The first thing that needs to be determined before using hash codes is the prefix, which is a sequence of #’s and/or *’s, that you need to use. They vary by radio technology, and sometimes by carrier.
    
    CDMA
    
        * Verizon: #*#
        * Sprint: ##
        * Other CDMA: #*#
    
    GSM
    
        * All Carriers: #*
    
    2. The Code
    
    This is the second part of a hash code. The code is what determines which hidden function is toggled. The majority of these codes spell out a word or abbreviation, so it may be easier to remember ERR instead of 377. Note that ERR is not to be typed out on the QWERTY keyboard, but rather, on the on-screen keypad.
    
    Commonly Used
    
        * 377
          Spells “ERR.” It displays the last error which caused a soft reset, what program was running, line number, etc.
        * 786
          Spells “RTN.” This the Phone Information page. It tells you how many minutes the unit has on it, how much data has transpired, the warranty date, ESN, phone number, software and hardware revisions, refurbished status, etc. Note: Please be careful with the options in the pull-down menu.
        * 66
          Spells “ON.” Turns on the radio.
        * 633
          Spells “OFF.” Turns off the radio.
    
    Others
    
        * 33284
          Spells “DEBUG.” This is the CDMA phone info screen, which contains a bunch of technical data on your curent signal and tower connection. Signal strength is given as RSSI, which stands for Received Signal Strength Indicator. The closer to zero the RSSI value, the better the signal.
        * 49878
          Spells “HWTST.” This launches the Troubleshooter and allows you to perform a hardware test.
        * 3836
          Spells “EVDO.” Launches Network Settings to force RTT or EVDO. This is useful if you don’t have EVDO coverage and want to force 1xRTT to prolong battery life.
        * 3282
          Spells “DATA.” Allows you to log into data services.
        * 8766
          Spells “VPON.” Voice privacy enabled.
        * 87633
          Spells “VPOFF.” Voice privacy disabled.
        * 744
          Spells “SIG.” Signal strength for select models only.
        * 744625
          Spells “SIGNAL.” Signal strength for select models only.
        * 8463
          Spells “TIME.” Displays the current date and time.
        * 56228466
          Spells “LOCATION.” Displays GPS location data (does not seem to work).
        * 000000
          This will allow you to manually program the phone on Verizon devices. Use this if you are planning to sell your phone and don’t want the buyer to see your number. For non-Verizon devices, you need to substitute 000000 with your MSL code (provided by carrier).
    
    Please exercise caution when using the following codes:
    
        * 72346
          Spells “RADIO.” Shows radio software version.
        * 8778
          Spells “UPST.” Toggles software download (bootloader). Note: You may need to soft reset your phone after this command.
        * 2539
          Spells “AKEY.” Allows you to re-enter the 26-digit AKey on CDMA devices. Note: An incorrect AKey will deactivate the phone and you will need to contact technical support for the AKey.
        * 7738
          Spells “PREV.” Opens Mobile Protocol Revision menu.
        * 56672225
          Spells “LOOPBACK.” Opens loopback calls menu.
        * 3424
          Spells “DIAG.” Toggles passthrough.
        * 7277
          Spells “PASS.” Turns on passthrough.
        * 7277633
          Spells “PASSOFF.” Turns off passthrough.
        * 83843733
          Spells “TETHERED.” Toggles tethered mode.
        * 88722366
          Spells “8TRACEON.” Trace enabled. Note: You may need to soft reset your phone after this command.
        * 887223633
          Spells “8TRACEOFF.” Trace disabled.
        * 28722366
          Spells “2TRACEON.” Trace enabled. Note: You may need to soft reset your phone after this command.
        * 287223633
          Spells “2TRACEOFF.” Trace disabled.
        * 798722366
          Spells “79TRACEON.” Trace enabled. Note: You may need to soft reset your phone after this command.
        * 7987223633
          Spells “79TRACEOFF.” Trace disabled.
        * 774
          Spells “PRI.” Allows you to reset the phone to factory settings. Note: This command can delete all data from your Treo. If you do not have recent backup, do not test this code! Do note that you may need to re-program your device and/or contact technical support for a new AKey after running this command.
    
    3. The Suffix
    
    There are two methods to initiate the hash code. The first method works on all devices. After you enter in the code, tap the Dial button on the screen. The second method works on most CDMA devices and is the method I prefer. It is a single # after the code, which is a bit more convenient because you won’t need to reach for the screen.

    The above does not show your MSL.
    But if you call support and tell them you need to do a reset because your data is screwey, they will give you your MSL no problem.

    ##GPS# doesn't give anything when in airplane mode for me. I was indoors near a window where I have other Bluetooth GPS receivers that pick up a signal perfectly, so that could be a bad sign for people.

    Also... um, isn't Sprint now legally required to give you the MSL if you ask, no matter what reason you want it?

    I didn't have a problem getting my MSL. I just called a local Sprint store and asked the manager of the store. Just warned me that if I change the software set at all, and brough it in for service, they wouldn't fix it.

    I hope some evil genius is hiding away in the basement cracking the tethering capabilities... one can only wish.

    I went into airplane mode and was able to get a fix in ##GPS#. Granted, I had just gotten a fix with the radios on a minute or two beforehand, so I don't know if that affected my results, but once I went into airplane mode, I still got a GPS fix.

    Here is a Hash Code post I made

    Try restarting the phone in airplane mode, and see if you can get a fix that way, because I know that was an issue with the 800w.

    So how many of these codes have been found to be working for the Pre?

    Cell phones that do not use a SIM Card have the data programmed in to their memory. This data is accessed by using a special digit sequence to access the "NAM" as in "Name" or number programming menu. From here, one can add information such as a new number for your phone, new Service Provider numbers, new emergency numbers, change their Authentication Key or A-Key code, and update their Preferred Roaming List or PRL. However, to prevent someone from accidentally disabling their phone or removing it from the network, the Service Provider puts a lock on this data called a Master Subsidiary Lock or MSL. Which is why Sprint/Verizon doesn't tell just anyone their MSL unless there's a reason for it.
