I consider things like these scary privacy problems.<p>Imagine it becoming a standard and then your friends going "Hey, you gotta hear what X said about Y on the phone. Here, I recorded it."<p>It would probably be considered weird if you had something against recording, after all you are talking with a friend and you trust him/her, right?<p>If you want to record a phone call, you can always do so (maybe not on a locked-down thing like the iPhone, well, your choice). But making it a prominent feature screams for abuse.
