Apple’s Iphone 5 which is expected to have a larger screen and a new dock connector will be unveiled at a ‘special event’ in San Francisco.

Technology giant Apple is expected to unveil the latest version of its best-selling iPhone tonight.

The secretive company is hosting a ‘special event’ which typically involves Apple executives unveiling new products to a specially invited audience.

It comes a day after the UK’s largest mobile network operator unveiled plans to launch the country’s first superfast 4G products and services in time for Christmas.

Orange and T-Mobile owner Everything Everywhere, which was renamed today as EE, will make the state-of-the-art technology available to some 20 million people in 16 cities across the UK.

The 4G network – which offers speeds up to five times faster than 3G – will be available on HTC, Samsung, Nokia and Huawei devices, as well as ‘one more to come’, widely expected to be the Apple product.

The 4G services will allow uninterrupted access to the web on the go, high definition movies to be downloaded in minutes and TV to be streamed without buffering.
