Do the new iPhones represent much of an upgrade over last year's flagship handset?
Smartphone brand Motorola has been criticised for revealing a "shameless" copy of the iPhone X as its new model.
Many phone-makers have copied the look of the iPhone X, which has a smaller bezel around the screen and a "notch" at the top that houses a camera.
However, reviewers said the new Motorola P30 was a "brazen" and "egregious" rip-off of Apple's flagship device.
News site Mashable said Motorola "even went so far as to adorn the screen with a wallpaper that's a dead ringer for Apple's default wallpaper".
Lenovo, which owns the Motorola brand, has not yet responded to the criticism.
President Recep Tayyip Erdogan says that Turkey would boycott US electronic goods in retaliation for sanctions implemented by Washington over the detention of an American pastor.
Mr Erdogan said: ""If (the US) have the iPhone, there's Samsung on the other side.
"We (also) have our Venus and Vestel," he said, referring to homegrown Turkish electronics brands.
There will be plenty of focus on Apple's share price when the US stock markets open later on to see if it will get close to a $1 trillion valuation.
But in the meantime, we took a look back at Apple when it was worth a "mere" $6bn and launch of the iPhone which, astonishingly, was only 11 years ago.
