It's just a parasite software, sony ericsson plug ins are for FREE as Nokia for example just go to Nokia and Sony Ericsson Web site, about the features about photo contact sync, that would be nice, but not in your site, not in this software manual talks about it!! And you have to pay to even try this install, such a hoax.
