It's another big news week for the mobile industry. HP is dropping its webOS phones and tablets, Skype is buying a mobile messaging company, Symbian introduces 'Anna' and RIM has three new sociable BlackBerry devices.

Earlier this month, Research In Motion announced two new BlackBerry Bold handsets and three new BlackBerry Torch devices, all running the BlackBerry 7 operating system. It's now following this up with news of three forthcoming BlackBerry Curve phones.

The BlackBerry Curve 9350, BlackBerry Curve 9360 and BlackBerry Curve 9370 smartphone will all use the new BlackBerry 7 OS as well.

Tru (formerly Truphone), the UK-based 'global mobile network', has appointed Steven Robertson as the company's new Chief Executive Officer. He replaces Geraldine Wilson, who stepped down last week.

Mr Robertson was CEO of Openreach until April this year and had previously been Managing Director of BT Wholesale Operations.

Sony Ericsson has announced a new Android smartphone called 'Live with Walkman'.

The Sony Ericsson Live with Walkman features a dedicated Walkman button that provides instant access to the music player. There's also Facebook integration that allows consumers to 'like' and share tunes, plus there's Sony's Qriocity service offering access to millions of songs and thousands of movies.

Vodafone says it's the first mobile provider in Europe to offer 'direct operator billing' for the Android Market.

This means customers will be able to buy apps and charge them to their Vodafone mobile account rather than using Google's own payment service, which requires credit or debit card details.
