As we build up to Apple's inevitable phone announcement in September, one of the biggest questions has been when the iPhone 8 would actually hit store shelves. While some rumors had suggested that the device wouldn't be available until November, claims of production having already started suggest otherwise.

According to well-known leaker OnLeaks, production on the iPhone 8 has officially begun which means it should arrive in late September as Apple's new phone traditionally do.

This really isn't that large of a surprise following Apple's earning call this week. During the quarterly talk with analysts, Apple gave guidance for the next quarter which ends on Sept. 30 of sequential growth of 12 percent. While that sounds boring on paper, it also gave us some indication that there would be no delay to new iPhone units.

The other major rumor surrounding the iPhone 8 has been just how much supply will be available when it launches, and that is still uncertain at this time. There has been wide speculation that Apple may be encountering some assembly issues with the new high-end phone, but we'll just have to wait and see how difficult it is to pick up an iPhone 8 once they do launch.

Apple is also expected to launch the iPhone 7s and iPhone 7s Plus in Sept., so expect an onslaught of leaked part images in the coming weeks as production ramps up on all of its upcoming devices.
