Yes, the sony erricson software is a pig. Go into control panel and find phone manager, then goto com ports and click enable on com4.
Open bluespace and enable serial port. Then try the software.
Just be a little careful with XTND cause it is really shit. I would back up your contacts first and the sync so that you can always undo.
Also have a look at it has lots of cool stuff and they are working on outlook syncing
