The company is releasing a 4.7-inch iPhone 6 and 5.5-inch iPhone 6 Plus. They will support more than 200 telecoms carriers worldwide, with sales launching in Australia on Friday morning and then in United States and other countries.
Like previous iPhones, the iPhone 6 Plus uses a Qualcomm 4G LTE modem, according to iFixit.

Dissembling the device in a Mac repair shop after lining up overnight to buy a phone, iFixit technicians also found a NAND flash memory chip, used for storing media like music and photos, made by SK Hynix. Apple in the past has depended on multiple companies to supply its memory chips.

News that a supplier has been chosen - or rejected - for one of Apple's products can sometimes cause drastic swings in stock prices. Apple doesn't disclose which companies make the components that go into its smartphones. It also imposes strict rules forbidding its suppliers from discussing Apple-related business with investors and the media.

Shares of GT Advanced Technologies Inc, a mineral crystal specialist, slumped 13 percent on 9th September after some investors were surprised the US company's scratch-resistant sapphire glass was not being used on the new iPhones.

Raymond James analysts expect sales of iPhone 6 and larger iPhone 6 Plus to top 9 million in the first weekend.

Apple's stores, Sprint Corp , T-Mobile US Inc, Verizon Wireless and some Apple authorized resellers in United States will start selling the phones on Friday.
