According to a report by This is my next, BestBuy informed their employees to stay tuned on 21st of October, for Apple product. Thisismynext got hold of internal documentation of the installation part of Friday, October 21. There is a strong possibility to be the release date for iPhone 5. Also, the manager of the store must be present from 6:00 am at the store from the usual 7:00 a.m., something that has happened before the release of iPhone 4 last year. Managers of BestBuy chain stores have arranged a meeting on October 10 to discuss upcoming big release!
On this basis we can expect an Apple event very soon to announce the iPhone 5.
