Next-generation iPhone coming in September?

Ok, so you won't be getting an iPhone refresh this summer. But according to a trio of sources speaking to Reuters, the next-generation iPhone should be shipping in September -- as we've heard before -- with production starting in July. One source said that the iPhone will feature a faster processor, naturally, and look largely similar to the iPhone 4. If true then prepare to see it unveiled at Apple's fall event, usually held in early September.
