Last month the Xperia X10 was spotted lurking around in the accessories section of UK carrier O2′s website, leading to speculation that the new android smartphone would be available on O2 when it is released in the UK. Now the handset has made a second appearance on the website in the O2 smartphone section which gives even further reason for us to think that O2 will indeed join their rivals Vodafone and offer the X10, although O2 have not confirmed that as yet.
