Verizon, the US telecoms operator, has reportedly added to the growing list of suggestions that the iPhone 5 will be released on 21 September by telling its employees they cannot holiday between 21 September and 30 September.
"A trusted Verizon employee has just confirmed to TechCrunch that the carrier is having an all-staff vacation blackout from the dates of Friday, September 21 to September 30. You know what that means, right?" says TechCrunch, who broke the story via one of its sources within the company.
The correlation between these dates and the much bandied about date of 21 September as a potential iPhone 5 release day seems too strong to ignore. However, it was only yesterday that talk was turning to 12 September being the choice day as it had just been announced that Everything Everywhere would be switching on its 4G network on 11 September, and the iPhone 5 is expected to be the first 4G phone to hit the UK.
One possible scenario is that 12 September will be the announcement day of the iPhone 5 while 21 September will the date it hits shops.
As well as being tipped as the first 4G phone in the UK, it is predicted the iPhone 5 is to sell over 250 million units. The upgrade to last year's iPhone 4S, it's also expected to finally sport a larger screen, moving up to 4in from the 3.5in size of previous generations.
