This morning, we told you about a Bloomberg report that stated Apple, Inc. would be holding a September 7th media event in San Francisco; an event that the publication predicted would herald in a new AppleTV and iPod Touch models. While we have no idea what will be released, we now know — officially — that Apple will be holding a media event on September 1st out in San Francisco. Judging by the invite, it will have something to do with music (see how we picked up on that). The event starts at 10:00 AM PT (1:00 PM ET). Any guesses what Apple has in store?
