The site posted similar leaked flex cables for the device earlier this month, and there are some slight differences between the two cables. For instance, the spacing between the volume button on the new sets seems to be modified compared to the flex cables pictured earlier. It is currently unclear whether the flex cables are authentic, or which cable is for what iPhone.
Apple.club.tw also posted a picture of a longer flex cable which its purpose is currently unknown. It also got its hands on SIM card tray slots. Interestingly, one set of the SIM card trays are a dark blue, which is not expected to be an iPhone 6 color.
Apple is expected to unveil the iPhone 6 in September in 4.7-inch and 5.5-inch models. Currently it is unclear if it plans on shipping both iPhone models at the same time.
