Apple has announced the latest version of its iPhone - the iPhone 5 - in 16GB, 32GB and 64GB versions. It’s also revealed new iPod touch and iPod nano music players, along with plans to update its iTunes music software in October.

The new 4G-equipped iPhone 5 is equipped with a 4-inch ‘Retina’ display and Apple’s iOS6 operating system running on the company’s A6 chip. It’s just 7.6mm thick, making it 18% thinner and 20% lighter than the previous model.

A court in the USA has ruled that Samsung has infringed a number of Apple patents for design and user interface, ordering the South Korean company to pay $1.05 billion (£664 million) in damages.

The long-running court case rejected Samsung’s claims that a number of its patents had been used without permission by Apple.

Last week, French iOS security researcher pod2g revealed a potential security risk with the Apple iPhone’s handling of SMS text messages.

All text messages can be sent with an optional ‘reply to’ telephone number that’s different from the sender’s number. The majority of text messages don’t use this feature - and many phones either ignore the extra data or display both numbers - but Apple’s iOS seems to handle it in a potentially risky way.

New figures from the International Data Corporation (IDC) have revealed that 85% of all smartphones shipped in the second quarter of 2012 ran either Android or Apple’s iOS.

It’s a new combined high for the two mobile operating systems, contrasting with BlackBerry and Symbian which both saw their market shares fall below 5%.

There are plenty of quarterly results to report in this week's edition of The Fonecast, including Samsung, Apple, Telefonica and Facebook. In addition, we have new research that shows how smartphone sales are racing ahead as feature phone sales slow down.
