We brought you high-res shots of the black and white next-generation iPhone backs in May, and then we brought you a video hands-on with similar looking casings in June that surfaced online. Today, Neowin posted images it claims to be a “prototype finalized design casing” of the next-gen iPhone (not a functioning device) in the hands of an ex-staff member at MBK Center in Bangkok, Thailand. Present is the repositioned headphone jack, redesigned speaker grills, smaller dock connector, etc., from past leaks, but we have no way of confirming its authenticity. It is possible this is a really good knock-off based on our earlier leaks.
