September 10th, folks -- that's when Apple will unveil its next iPhone according to AllThingsD. We've received no official word yet, but recent leaks (and past form) suggest a refreshed iPhone 5 (possibly with a larger screen?) and possibly a low-cost model clad in plastic. It's a safe bet that the release version of iOS 7 will also make an appearance at the event, which is shaping up to be an iPhone- and iOS-focused affair, according to ATD. Feeling a sense of déjà vu? As always, we'll keep you informed when more concrete info makes its way to us.
