    I've never had a problem with the dreaded "GSM buzz" on my 3GS… until recently. Over the last few weeks, the buzz has suddenly begun affecting a variety of speakers; my home theatre, my digital piano, etc.

    My questions is: why now? I've owned the 3GS since July 2009, and not had a problem until now. Can anyone offer an explanation?

    I dunno,
    I've always had a GSM buzz. I can't say why it appeared to you so suddenly

    I always had the GSM buzz back with my 1st-gen iPhone running on only AT&T's Edge network. Once I stepped into the iPhone 3GS and was on AT&T's 3G network, the GSM speaker disappeared.

    I will say that, every once in a while, in a spot in which I typically have rock-solid 3G coverage, I'll get knocked off onto Edge network, and am usually alerted to this by some speaker buzz. I think one reason I'm unaware at first is because I'm often connected to a Wi-Fi AP, so I don't see the "E" or "3G" up in the phone's status bar.

    So, are you sure you're not dropping down to Edge?

    Good call, and thanks a million. I've been using "My Profiles" app on my jailbroken 3GS. I had set it up to turn off my 3G (but not Edge, I guess) when I'm connected to Wi-Fi. I've changed the setting so that 3G is enabled, even when connected to Wi-Fi, and the problem is gone. Yay!
