We’ve now learned that at least some U.S. Apple Retail stores are also recruiting former employees to return as part time employees for Holidays, new Product Launches and Back to School time. A former employee received emails asking to return between August 15 and September 15th.
Could be nothing at all. As Mac Rumors points out, this is the back to school time, but it could also be the time for the iPhone 5. Only Steve knows for sure.
