Best Buy and Best Buy Mobile stores are looking to possibly start iPhone 5 presales this week, and the phone could arrive within the first week of October, according to a report.

A Best Buy source released a document to BGR.com, which shows that the store is anticipating the presales and also that Sprint will be carrying the iPhone 5 at the launch of the new device.

Best Buy did note, however, that Apple product introduction and launch dates are subject to change, BGR reported.

Analysts have said they expect the iPhone 5 to come out in the fourth quarter. And people are eagerly awaiting its release to see what the new device will look like and what features it will carry.

There have been reports that Apple lost a prototype of the iPhone 5 in a tequila bar in San Francisco last month. The San Francisco Police Department on Friday said they did help the iPhone maker retrieve the lost prototype after it was traced to a house. Apple employees were said to have helped police raid the house of 22-year-old Sergio Calderon.

Calderon told the media that he had went to the same bar where the device was lost but had had no knowledge of the missing phone.

The two Apple (security) employees met with the resident and then went into the house to look for the lost item. The Apple employees did not find the lost item and left the house, the police statement said.

Last year, Apple lost a prototype of the iPhone 4 in similar fashion when an employee left the prototype at the Gourmet Haus Staudt beer garden in Redwood City, Calif. The device was found and sold to tech blog Gizmodo, which wrote about the phone at length in a widely read post.

Apple has since taken steps to beef up its security, as it has listed job postings on its Web site looking for people responsible for managing risk associated with Apple's unreleased products.

The individual will collaborate with other security managers by contributing to, and managing execution of, strategic initiatives set forth by Director, Global Security, the job posting reads.

Additionally, the new manager will also ensure intellectual property will be kept in safe hands as well.
