Japanese part firms Mounantai has turned up three photos of what they’re emphatically claiming is the logic board for the iPhone 5S. There’s nothing soldered or plugged into this part, meaning no early peek at the iPhone 5S’s (presumed) A7 chip.
There’s not much to go on here, except that it looks like the iPhone 5S circuit board might be slightly narrower than that in the iPhone 5, and that while the iPhone 5S might just be a small speed-bump before the debut of the iPhone 6 next year, it’s still gotten a major overhaul on the inside.
