The best iPhone 6 photo leak yet ... from TMZ?

What the latest iPhone 6 leak means

What may be the clearest pictures yet of Apple's forthcoming iPhone 6 emerged on Friday—from, of all places, the Hollywood gossip website TMZ.

TMZ posted the pictures around 4 a.m. EDT Friday, saying the phone had been smuggled out of the factory where it was manufactured.

TMZ did not make clear who the person was who now holds the phone, or whether Apple had responded in any way to the leak. The company has steadfastly declined to comment on rumors about the phone, which is expected to be unveiled next month.
