Apple on Tuesday fired off invitations to a September 15 online event expected to introduce a new-generation iPhone tailored for superfast 5G telecom networks.

The typically tight-lipped technology titan revealed only that the presentation would be streamed starting at 1700 GMT from its headquarters in Silicon Valley.

The invitation was also posted at the Apple website, where the event will be streamed. Apple has routinely held events this time of year to unveil new iPhones, and expectations are that this time around the spotlight will shine on a 5G model, with other new handsets possible as well.
