Late last month, Japanese blog Mac Otakara sparked particular interest in a set of photos of an assembled front panel from the iPhone 5 by claiming that a square feature near the top of the part was likely to be related to near field communications (NFC) capabilities. That interest was quickly tamped down when The Loop reported later in the week that there would be no NFC in the iPhone 5.
Despite the fact that the square feature is slightly off-center with respect to the device, we've assumed that it must be the earpiece speaker, and consultations with experts at RepairLabs have suggested the same.
