AppleInsider is reporting that Apple has quietly told employees in some locations that they won't be able to take vacation time in the second week of October — usually a sign of a new product launch. This and other evidence suggests to AppleInsider that iOS 5.0 will be released October 10 and iPhone 5 will become available between October 14 and 16. These details fit with the media event rumored to be planned for October 4.
