Right i did a sync it crashed and then after the next sync i have double of all my contacts!
It might be easier to delete all contacts within your PIM, and then re-synch. That should leave you with one of each contact on your phone and PIM.
Though I'd backup the contact db on your PIM first!
You look like you want to go away, But I know you’re gonna stay. For although your heart is in L.A, Your head is in my fridge. There’s flowers in your hair, they're not real their made of silk. There’s a note in your mouth, to remind me to get milk.
