A 10th anniversary iPhone is expected to star at a keenly anticipated Apple event today at its new campus in Silicon Valley.

A fresh leak of new software for Apple devices appeared to confirm rumors that the company will unveil three new iPhone models, with the most radical changes packed into atop-of-the-line 'X' version.

Evidence suggests that two iPhone 8 models would essentially be improved versions of their predecessors, while the 'X' version will boast an improved quality edge-to-edge screen, advanced augmented reality capabilities, and facial recognition instead of a 'home' button to unlock the screen, analysts said.

There has been unconfirmed talk that an iPhone X, or whatever name Apple choses for it, could be priced as high as $1,400.

The leaks appeared to come from within the company, offering key details of new hardware and software.

A key question for the tech giant is whether it can dazzle the world the way it did with the first iPhone a decade ago.

The media event is the first in the Steve Jobs Theater at Apple's new 'spaceship' campus in Cupertino, evoking the memory of the company's late co-founder and iconic pitchman.  -- Agencies
