When I bought the Pre they did a push over of all contacts and calendar events from my Centro. I've since determined that I don't need a lot of the contacts and am entering them into Google contacts and will then do a sync with Google to bring the Contacts over.

Is there a way to delete just Contacts from your Pre and Pre Profile?
Or can I change e-mail addresses on the Pre Profile and it'll give me a clean slate?
I really don't want to go through the hassle of a Hard reset.
