Sony Ericsson’s XPERIA X10 has made a discrete appearance on carrier O2 UK’s website, though the Android smartphone is not actually mentioned by name.  Given pride of place among a smartphone group photo, the XPERIA X10 nonetheless lacks any sort of product page or “coming soon” mention.

There’s also mention of the X10 on the O2 accessories page, where the 4.1-inch device is listed as a possible choice under the drop-down handset list.  With arch rival Vodafone already having confirmed that the new XPERIA is on its way in April 2010, it’s not too great a leap to presume that O2 are ramping up to offer the smartphone too.
