    I will not be responsible if you ruin/damage your phone while using this.
    It's an extensive menu, lots of tests, an option for the factory reset (the power+vol+home option) and more info than you can shake a stick at.
    I know it can be destructive - it already wiped my APN settings, so watch out. Use at your own risk !

    Dial 3845#*509#

    NOTE : after playing with it some more, it appears to be available on 2.2 through 2.2.2.
    Your mileage may vary depending on what you use on your phone.


    Good luck !

    Wow, you weren't kidding! Just for fun, I'll list the options shown:

    Version Info
    Factory Reset
    Device Test
    Port Setting
    Modem Setting
    Module Test
    SIM Test
    Call Test
    Aging Test
    Streaming
    Wap Debug
    MMS Test
    SMS Test
    GPS Test
    WLAN Test
    Network Mode
    FM Radio Test
    DRM Test
    KR Setting
    Contacts Test
    SyncML Test
    ELT mode Test
    LCD Module Test
    FPRI Test
    DB Check
    Log service
    DM/FOTA Test

    Most of these I'm afraid to even try, for fear of losing something I wasn't supposed to have access to! But I got a raw list of GPS satellites from an option in the GPS Test, and the LCD Module Test cycles through test screens as you tap the screen.

    I don't think I'll poke any further, though, until I find out what's a good low-level backup program I should install...

    If you are rooted nandroid backup (through clockworkmod recovery) works great. It backs up pretty much your whole system.
