Thanks to a leaked document from a Best Buy source, we have discovered that Best Buy and Best Buy Mobile stores are anticipating taking preorders for the iPhone 5 starting in the first week of October. What’s a tad bit more interesting, however, is the mention (and further anticipation) that Sprint will be carrying the iPhone 5 at launch. Best Buy makes sure to note that Apple product introduction and launch dates are subject to change, but a preorder date changing is pretty different from a new carrier getting a phone for the first time.

UPDATE: Our source clarified that it’s actually possible presales will be starting this week with the phone arriving in the first week of October, not preorders starting in October.

Thanks, Tee!
