Rumours of an iPhone 5 launch date of the 4th of October appear to have been confirmed by Apple's own employees, who are reportedly forbidden from booking holiday around that date.
While the rumour wagon is currently being pulled by none other than Al Gore, whose recent comments have pointed the way towards multiple iPhone models being announced towards the start of next month.
That proposed timeline has been given a bit more meat with AppleInsider reporting leaked information that Apple is denying its employees holiday during the periods of the 9th of October to the 12th of October, and the 14th of October to the 15th of October inclusive.
Those periods, it is thought, correspond to release of the final iOS 5 build for existing iPhone, iPad, and iPod Touch devices, to be followed by the launch of a new iPhone handset a few days later.
That matches Apple's previous launch schedules, with the iOS release arriving a few days before the new hardware. What isn't yet clear, however, is what that hardware might be.
Last year, Apple released the iOS 4.0 update three days before the iPhone 4 was made available to buy, suggesting that Apple could be launching the iPhone 5 on the 14th or 15th of October following a preview announcement on the 4th.
The year prior, however, the company settled for a redesigned version of its iPhone 3G, dubbed the iPhone 3GS, and there are plenty of rumours circulating that a slimmer iPhone 4 - called, unsurprisingly, the iPhone 4S - is due before the end of the year.
While it seems clear that Apple has something big planned for October, it's not yet clear which of the two possibilities is the most likely - or whether Gore's comments regarding multiple iPhone announcements will prove true, and Apple will for the first time launch two devices side-by-side at different price points.
