Mention 'anonymity' to anyone these days and it's pretty likely they'll start talking about Facebook. Maybe Google Street View, maybe RF chips in passports... but probably Facebook.

This 'over sharing' of personal information is a far cry from the situation a few years ago. Once, no-one on the internet really admitted who they were. That New Yorker cartoon - "Nobody knows you're a dog" - wasn't far off the truth. You couldn't tell a dungeonmaster from a librarian when they were online.

Research In Motion says it'll reveal the sixth version of its BlackBerry operating system in the third quarter of 2010. However it's released a video showing elements of v6.0 at the Wireless Enterprise Symposium event this week. Look out for multi-touch support, redesigned apps and a new home screen experience.

Research In Motion Limited has announced a new service called BlackBerry Mobile Voice System 5, which will offer voice-over-WiFi calling from later this year. BlackBerry MVS 5 works with Cisco Unified Communications Manager to provide a business user with the ability to use their regular fixed-line office telephone number and extension from their BlackBerry device. It means businesses can let their staff receive calls on their regular office phone numbers whenever they're connected to a WiFi network.

Calls made through BlackBerry MVS 5 are routed through the company's Private Branch Exchange (PBX) system. Employees also benefit from the convenience of a single work phone number shared between their desk phone and BlackBerry smartphone. Incoming calls can ring simultaneously on the employee’s desk phone and their BlackBerry.
