    I noticed this last night for hte first time on my iPhone. It has happened with my past phones as well, so just wondering if anyone else has experienced this with their iPhone or other phones.

    The phone was on my nightstand as I was in bed (not plugged in to anything) and all of a sudden, I heard these strange little "morse-code" like fast paced beeping. It was not coming from the speaker, jsut from the phoen itself. My past phones have done this from time to time as well.

    One possible explanation I read online once is a noise it makes while trying to find a signal, but I picekd up the phone and looked while it was making the noise. Perfect signal. Anyone have any ideas?

    Maybe the government is tracking me with my cell phone and that is the sound it makes when they download my location and stuff (Just kidding - not a paranoid conspiracy theorist).

    It's typical of GSM.

    Link to a previous discussion of this effect and how it can interfere with iPods.

    Sounds about right. I found this article as well:

    That is most convincing to me as I did place the iPhone next to my old iPod speakers when it started, and when I moved it to the other nightstand without the speakers, it did not do it any more.
