A source allegedly involved in the filming has told AppleInsider that Apple's ad agency is now shooting ad spots for the iPhone 5 national campaign -- but the filming isn't slated to wrap up until early October, supporting rumors of a mid-October or later release. The report says filming is taking place in Los Angeles under the auspices of TBWAChiatDay, Apple's long-time ad agency. Apple has been known to film its phone commercials roughly five weeks in advance.
