If they actually had any customer service and thier phones were any good then there would be no issues.
I purchased an Xperia X1 in November last year. Since then my phone has had the battery life cut in about half, needs to be charged on a daily basis to avoid dying even when not in use. The interface will freeze on a regular basis. And the update software is useless, will not function and if you contact the technical support you do not get any response.
One thing this purchase has done for me is to make sure that I never buy another Sony/Sony Ericsson product again.
