The latest iPhone's A6 processor has been designed by Apple and manufactured by Samsung Electronics. What's remain to be confirmed is the number of GPU cores packed on the A6 SoC. For sure, the A6 is very fast and preliminary benchmarks show roughly twice the performance of Apple's A5 chip.

Sharp, LG Display and Japan Display are believed to supply Apple with display panels for its iPhones.

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 said it booked over two million online pre-orders for the device in the first 24 hours.

Problems with new maps app

Just one day after Apple's new iOS6 operating system was released, users from countries including the United States, Britain, China, France and Japan have protested that the new maps misplace some landmarks and leave others off altogether.

According to reports, many town names are wrong or even missing, roads are all the same colour and satellite image resolution is not as good as it was previously. The app also lacks features found in Google Maps, including public transit directions, comprehensive traffic data or street view pictures.

With the iOS6, Apple replaced the Google Maps app with its own custom-made mapping software.

A separate Google Maps app is not currently available for sale from Apple, although Google's system can still be used via the iPhone's web browser.

Apple licenses mapping data from TomTom. TomTom said it stands behind the quality of its maps but didn't develop the app.
