Not exactly the headline act of Sony Ericsson's latest batch of phones, but if you're a social networking obsessive, the Sony Ericsson Cedar smartphone could be a useful purchase for a moderate outlay.Ok, let's start with the positives. This 'affordable' handset packs high-speed HSDPA connectivity for faster browsing and quick access to your social network of choice. Indeed, there are widgets on-board, powered by the company's Widget Manager 2.0, which offer one click access to the big boys of Facebook, Twitter and MySpace from the standby screen.But scratch below that web 2.0 surface and you'll find a set of fairly average features. SE throws in calendar, phone book and email functionality plus hassle-free phone book transfer and web backup, but there''s no Wi-Fi and the camera is a below-average 2-megapixel job. But let's finish with some positives - the Cedar does have a 3.5mm jack for a decent set of headphones, a 'human curvature design' for a better fit into your hand and as a GreenHeart phone, it is doing a little extra for the environment.If you like the idea of the Sony Ericsson Cedar, look out for it later in the year in black/silver and black/red, presumably on PAYG or a small contract.
