My iPhone is causing crazy interference if I get it near any speakers. What's going on?
It's jailbroken with redsn0w on 3.0.1, and I believe I have wifi, bluetooth, SSH, edge, and 3G all turned off. I find SBSprefs harder to navigate than good 'ol bossprefs, though, so I'm not sure. It's only mercifully quiet if I stick it in the center of the room alone or put it in airplane mode. This thing is first and foremost a phone, so I'd rather not do that!
