Almost confirmed: iPhone “5” set for September 21st

If the story is true, the next iPhone – probably named “iPhone 5” – will be released on or about September 21st.

How can this be sort of confirmed [but not by Apple]?

Verizon in the US has announced no vacations to its employees from September 21st to September 30th. [Some say an announcement will come out on September 12th.]
