Apple hasn't announced a new iPhone yet, but it's safe to assume there'll be one this year. There's been a new iPhone once a year, every year, since Apple introduced it in 2007. The original iPhone was announced in January and shipped in June. iPhone 3G, iPhone 3GS, and iPhone 4 were announced in June and shipped shortly thereafter. Last year, Apple switched to October for the iPhone 4S announcement and release, but otherwise didn't skip a beat. Back in July iMore learned that this year the iPhone 5,1 would be announced on September 12 and released on September 21. Apple has since confirmed the announcement date but not yet the release, and despite a steady stream of leaks, nothing is official until an Apple shows it off on stage.
With that in mind, however, we have reason to believe some of those leaks have been accurate. We've gone over them previously in separate articles, but it's worth rounding them up here. That way we can start setting reasonable expectations, even while we wait to be wowed.
