According to a senior executive at Swiss carrier Swisscom, Apple has set a US launch date of September 5 for the iPhone 5, with the device launching globally the following month.
Swisscom is Apple's partner in Switzerland. The executive - who asked to remain anonymous - leaked the information to iPhone Italia.
The date contradicts previous rumours that production on the new phone won't begin until September, pointing to a late 2011 / early 2012 release date.
That said, the CEO of US telecoms firm Verizon, speaking in a conference call with analysts over the weekend, revealed that the iPhone 5 will be released sometime "in the fall".
Another day, another iPhone 5 rumour. Most rumours seem to be pointing to an autumn release now, which would mean that a formal announcement from Apple shouldn't be too far off.
