Sony Ericsson doesn't think Facebook is accessible enough on its range of Xperia smartphones. So with that in mind, the company has launched Facebook inside Xperia.The update is said to make Facebook 'immediately accessible from the most used areas of the phone'. That means areas such as the picture gallery, music player, phonebook and calendar. In short, it's deeper integration with Facebook, along similar lines to other recent handsets from the likes of HTC and INQ.For example, you can share and comment more easily through your Xperia smartphone. If you find a new music track or are listening to your favourite tune, you can 'like' it directly from the media player, the Wall on your Facebook profile being updated automatically without you ever having to open the Facebook application.You will also have the ability to keep track of the music and videos your friends have liked, recommended and have been commenting on through services such as YouTube and Spotify. That could be interesting or it could be information overkill (depending on your friends' musical tastes). Time will tell.Beyond music, you can 'like' and comment on photos easily and your phonebook will be 'more social', featuring your friends' interests and photos found under their address book entry on the phone. The phone's calendar also includes your friends' birthdays too and there's also event syncing between Facebook and your phone.Stephan Croix, head of marketing partnerships at Sony Ericsson said: 'Social media usage via smartphones is now part of everyday life. Sony Ericsson has enhanced the integration of Facebook in the Xperia portfolio to give consumers a unique and entertaining experience instantly-one they can only experience via an Xperia smartphone. Sony Ericsson is working closely with Facebook to ensure that the integration continually evolves ensuring that users have the ability to interact between their preferred social media channels and their smartphones.' Existing Xperia Arc and Play users will soon be able to access the new features by updating their software. If you opt for either of the newly-announced mini phones, Facebook inside Xperia will be pre-installed on the phones.
