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.

With this week’s announcement that Everything Everywhere has been given the green light to launch the UK’s first 4G service, competing operators such as Vodafone and O2 are getting hot under the collar.

A court in South Korea has ruled that Apple and Samsung have breached each other’s patents, ordering both companies to pay fines and remove some of their products from sale.

Apple must pay Samsung 40 million South Korean Won (around £22,250) while Samsung needs to pay Apple 25 million Won.

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.

Microsoft has updated its company logo for the first time in 25 years, moving away from the old italic-style logo.

The new logo, which will be used for the Windows 8 and Windows Phone 8 operating systems when they’re launched later this year, utilises the Segoe font that’s already featured on newer Microsoft products and marketing communications.
