Hmmm, i actually i forgot to do it. I dont use ActiveSync as im a Mac guy. I restored my contacts and what not with pimBACKUP. Im going to update right now. Hopefully no dupes.
EDIT: Sweet, it actually asked me if i wanted to keep the list in my phone or change it to the dashwire one. So i just kept mine. It's only just started to sync, but i already like the new UI a lot more.
