I can save my phone contacts from iphone to itunes being a windows user?

I went to see the Genius @ Apple store 3 times, software reistalled twice, new battery and phone replaced no improvements so my conclusion is: The data transferred from my Blackberry got corrupted. I spoke wiht my Celullar provider customer support and he said the same so the next step is to wipe everything from the iphone and start as a new one, meaning loosing everything, however, I would like to be able to save my contacts. I dont have a mac computer I am a windows 7 user so big big query for you is -
