Apple has sent out invitations for an event on Sept. 12, according to a report from Jim Dalrymple at The Loop.

The event , almost certainly to be an announcement of the release of Apple’s next iPhone, will take place at the Yerba Buena Center for the Arts in San Francisco, a favorite Apple launch location, the report said.

There’s also a hint that Apple may stick with its traditional naming system and call this handset the iPhone 5. There had been some speculation that Apple would refer to its next iPhone as “the new iPhone,” as it did with its most recent iPad. But the invitation that Dalrymple posted has a black number 12 backlit against a white background, casting a faint, shadowy number 5.

Apart from the two numbers and a small Apple logo, there’s only a tag­line above the number 12 reads, “It’s almost here.” There are no further clues about the device’s design or features — or about whether Apple, is, in fact announcing a new version of its smartphone.

Apple next iPhone is expected to have a new design, with a bigger screen and a slimmer profile. Reports indicate that the phone could be released not long after the launch event, on Sept. 21.
