Source's track record may back guide's authenticity
French site Nowhereelse has published a photo of what it claims is the Quick Start guide for the iPhone 6. If authentic, the guide shows the layout of the device, including a sleep/wake button relocated from the top to the side, presumably because of the phone's larger size. The date on the phone is also set to "Tuesday, September 9," when Apple is generally expected to announce new iPhones. Past Quick Start guides have also used announcement dates.
While the document could be faked, Nowherelese has a good track record, and leaked the guide for the iPhone 5s hours before the phone was officially revealed. Some oddities are the lack of any visible app icons or sensors (apart from the Touch ID button). That could simply mean that the guide is a draft, though, or that Apple has streamlined its content.
