It may actually be AT&T that blocks tethering on the iPhone, even though they allow it on other phones. Take SlingPlayer for example, it's been out for other phones and available to use over 3G for a long time, but the iPhone version will only work over WiFi. I think the proliferation of iPhones is causing AT&T to enact different policies so their network doesn't get bogged down.
