Apple's iPhone 5 uses chips from Avago and Skyworks Solutions, according to repair firm iFixit, which pried one open on Thursday.

The latest iPhone, which first went on sale in Australia on Friday morning, has a larger, 4-inch screen and is slimmer and far lighter than previous models.

Apple booked over two million online pre-orders for the device in the first 24 hours, underpinning investors' expectations the new device will maintain the Cupertino, California company's meteoric growth.

Companies supplying parts for the new phone also include memory chipmaker Hynix and radio-frequency chipmaker Triquint, according to iFixit, which stripped down one of the new devices in Melbourne.

News that a supplier has been chosen — or rejected — for one of Apple's products can cause drastic swings in stock prices. But Apple doesn't disclose which companies make the components that go into its smartphones.

iFixit co-founder Luke Soules spent the night lined up at a local store to buy one of the first iPhone 5s.

Fueled by Red Bull energy drinks to keep himself going, Soules rushed the phone to a nearby Mac repair store fitted out with tools, lights and a camera to begin dissecting the iPhone, a process that can take hours.

He said his first impression was that the iPhone felt well-built and was harder to open than he expected.
