HP has announced a new Android device with a detachable keypad, enabling it to transform between notebook and tablet.

It’s called the HP SlateBook x2 and was revealed alongside a convertible Windows-based computer.

BlackBerry is launching Android and Apple iOS apps for its BlackBerry Messenger service this summer.

It means that free BBM instant messaging will no longer be exclusively available on BlackBerry handsets but will also work across other platforms.

Nokia has had a busy few days. First came the Asha 501, a ‘smartphone lite’ that introduced developers to a new version of the company’s Asha platform. This was followed by the Lumia 928, which is a Windows Phone 8 handset exclusive to Verizon Wireless in the USA. It’s quite like the Nokia 920, so we’re not missing out too much.
