Micro-blogging service Twitter has launched a new service called Twitter #music. It uses activity on Twitter to find the most popular tracks and new artists as well as making it easier for users to enjoy music from their favourite musicians.

The service uses iTunes, Spotify and Rdio to provide its music.

Inq, the Hutchison Whampoa subsidiary that started life five years ago as a mobile phone manufacturer before changing its focus to mobile software, has released the beta version of its new Material application.

Material is described as a ‘content discovery service’ that creates a twice-daily electronic magazine from information from the user’s Twitter and Facebook feeds.

Twitter says a security attack late last week managed to gain access to information about around 250,000 of its users. It appears the hackers gained access to usernames, email addresses and encrypted versions of passwords.

The service responded by resetting passwords for all affected accounts, which appeared to include many Twitter ‘early adopters’.

The last of the 2012 quarterly results are coming in, so it's time to compare figures from the biggest mobile handset manufacturers.

We're also looking at Twitter's new video app, discussing the forthcoming Firefox OS and preparing for the BlackBerry 10 launch later today.

I didn’t study economics at college, which is probably one of the reasons I have a very simple perspective on quarterly results. As far as I’m concerned, they fall into one of three categories: much as expected, better than expected or worse than expected. Anyway, it’s the time of year when some of the biggest names in the mobile telecoms industry publish their financial results – so here we go.
