A photograph of an internal Best Buy retail calendar screenshot may give us the best clue yet as to the launch day of the iPhone 5. The event in question is an Apple fixture installation and is scheduled for October 21st. The date in question is a Friday which would line up with other iPhone release days.

This not a normal fixture installation either according to a tipster who talked to This is my next. The request for a manager to be on hand at 6am is not the norm and is a mirror image of what happened when the iPhone 4 was launched last year. The tipster also went on to say that Best Buy managers have a meeting scheduled for October 10 to discuss upcoming releases.

TiPb recently heard that an original release date of October 14 was being moved up to October 7. Whether it's now been moved back again, this time to October 21 we're not certain, but because Apple doesn't pre-announce products, they're free to adjust the exact date up until even invitations go out and their executives take the stage.

I still expect an announcement of the iPhone 5 at the end of this month with a mid October release. Either way, I am now sick of suffering with an iPhone 4 that is out of warranty. Anyone else tired of waiting for iPhone 5 already?

UPDATE: Boy Genius also got their hands on a Best Buy screen today, this one pointing to a possible first week of October launch for iPhone 5, similar to what TiPb heard a few weeks ago. They also seem to indicate Sprint will be one of the launch carriers, which has been another of the big rumors circulating lately. All of this, again, claims
