Sony Ericsson has used the Mobile World Congress event in Spain as the launch pad of the "XPERIA" range that they say heralds a new era in mobile communications and has announced the X1 model, a new "arc slider" phone.

Designed to meet the growing need for mobile web communication and multimedia entertainment (or to stand up to Apple's iPhone) the company says the range will offer a "premium, converged mobile experience".

The XPERIA X1 combines a 3-inch wide touchscreen VGA display and a full QWERTY keyboard, a 4-way key and optical joystick navigation within a metal-finish body.

Running on the Windows Mobile platform, a first for the company, the phone has been specially tailored for Sony Ericsson with access to features via the customisable "XPERIA" panel on the touchscreen.

The "arc" design means you slide the screen sideways to reveal the wide pitch QWERTY keyboard that it said to have "ample" distance between keys makes writing fast and easy.

Connectivity comes in via HSDPA/HSUPA and Wi-Fi support while aGPS provides navigational functionality.

The Sony Ericsson XPERIA X1 will be available in selected markets from the second half of 2008. - PAY MONTHLY PHONES The Samsung Galaxy S10+ is now available on EE who have been awarded the UK’s best network for the fifth year running. RootMetrics tested the four UK networks and EE was faster and more reliable than all of them, with better data performance. Their network has come a long way since they launched in 2012. Back then they had 11 UK cities covered by 4G. Today they cover most of the UK’s land mass, thanks to 19,000 state-of-the-art 4G sites. They’ve got faster, too – from 50Mbps to a maximum speed of 400Mbps. And they’re soon to experience even greater possibilities with the launch of 5G.
