How can I get numbers off a broken phone?

[WEHGuy]

Hi, my Sony Ericsson W980 has stopped working. When I do manage to get it to turn it on, it just says insert sim. I have tried 3 different sims in it to no avail. I have put the sim that was in it, into another phone and it works fine. I'm not too bothered about the phone, although it would be nice to fix it but, really need the contacts off of it because it is my business phone. Does anybody have any ideas for me to do this? Any help would be greatly appreciated. Thanks in advance.

Could try installing PC suite and syncing all information

Although if the phone wont boot then it is not likely to work
