Jim Dalrymple confirms the iPhone event will take place on September 10th.

Jim Dalrymple has close ties with Apple's public relations department. He usually uses 'Yep' or 'Nope' to confirm or deny a rumor, and there has been no mistake in recent years. Some people think he is Apple's unofficial spokesman. Meanwhile, Apple has not commented on the launch event. The iPhone 5S to be released this year may feature an improved A7 chip, a fingerprint recognition sensor, a 12-megapixel camera, dual LED flash and more.
