Kodawarisan has given us the first rumored date for Apple's annual iPod media event. They claim that this year's event will be held on September 7. In the last three years, the event has been held on September 1st once, and twice September 9th. This year we can expect to see 3 or 4 of the iPod lines refreshed (will the iPod Touch be refreshed?), as well as the iPhone 5 released.
Update: The Loop reports that sources have denied this date.
