my K800i has today developed a fault, it has no sound when making/receiving calls unless i turn on the loudspeaker! I phoned Sony Ericsson to be told the nearest service centre to me is Barnet, I live in Luton!!! So I either got to spend the best part of 2 days travelling into London to get to Barnet to drop off the phone & collect it, or I can send it through the post, which i am not entirely happy with!!! Anyone else encountered this problem?
