This week Nokia has announced the latest iteration of its Symbian software platform: Symbian Belle, which follows the alphabetical theme started by Symbian Anna. Whether we'll reach Symbian Zoe, Zara or Zsa-Zsa before Symbian support ends in 2016 is another matter. But I digress.

Samsung Electronics has announced a new naming strategy for its Galaxy range of smartphones.

There'll be five different classes of device, each identified by a single letter. A 'class indicator' will then provide more information.

Facebook is making a number of changes to its service, with improvements to its privacy controls.

It's also phasing out the 'Places' feature, which was available to mobile phone users, and will now allow users to 'check in' by adding location to anything - including status updates, photos and Wall posts.

It's reported that a court in the Netherlands has issued a preliminary injunction against the Samsung Galaxy S, Galaxy S II and Samsung Ace smartphones.

The decision follows a request by Apple and concerns a single software patent involving the photo gallery on phones. The legal order affects Samsung subsidiaries registered in the Netherlands, from where Samsung apparently manages much of its European distribution.
