...that anything with iPhone 3G/3GS compatibility, AS FAR AS UTILIZING THE 30-PIN CONNECTOR, is also compatible with the iPhone 4? Some products I've seen like chargers, docks, and speakers say they support 3GS/3G but make no mention of the iPhone 4. I was thinking this is because their pages are outdated but I wanna be sure. Like this. Or the iHome iP1.
