There is no official invite from Apple yet but All Things D reports that a month from today the company will be calling the media together on September 10th to unveil it’s latest iPhone. With multiple rumors of both the cheaper plastic built iPhone 5c and the replacement iPhone 5s hoovering around, no one seems to be sure if both phones will be launched at the same event
The report does not mention of the iPad as well, and it’s possible Apple could be planning a separate event (as it has in years past) to announce upgrades to the iPad mini and fourth-generation Retina models. More likely is that the September 10th presentation will reveal a release date for iOS 7, which has now seen over five betas since its announcement in June at WWDC.
