Hi I have just bought an Sony Ericsson XPERIA x1, But with a powerful web browser, ample of storage capacity, good camera with a very sharp display I just could not resist and started using Sony Ericsson XPERIA x1. I want to avoid one of my friend and so I need to block his number, but the problem is that i donít know how to block a number in Sony Ericsson is there any application that I need to block a number. I am not use to a Sony phone since all these years I use to have LG phones. I have almost wasted an hour finding a solution, but it just does not click me. Please help is needed. How should I proceed further.
