    I found a hidden Smartphone feature!

    I'm not sure if you guys knew this or not, but I just found this by trying stuff. It works on my MPx200 and I think it should work for all smartphones. Dial *#999# and press the blue button (the middle one) or whatever the equivalent is on your phone. It'll then show a log of all this weird stuff. If you scroll to the top (which takes a long time since it's pretty long) it has some version information.

    Also, you can use 3 as "page up" and 9 as "page down" to scroll faster.

    Here is a picture of what I get when doing *#999# :

    Looking at ToadX's jpg: When using phone as a data modem with CSD (vs GPRS), an AT-command of 'AT+CGDCONT...' is used to initialized the *modem* and software is set to dial '*99#' to activate the connection. I'm TOTALLY gussing that '*#999#' is triggering the display of the CSD log file...

    Just thowing an idea out there..(no knowledge on my part).

    Those are definitely Hays AT modem commands. The strange thing is that I've never used CSD. Only GPRS (which I cancelled once I realized how useless mMode is).

    I pushed the center navigation button and my i600 attempted to dial #999#.

    How did you get the read out?

    It's *#999# You have to put the * . If you were already doing that, then I guess it doesn't work on that phone.

    Interesting.
    It does look like some commands sent by Windows CE to the actual phone hardware.
