I recently purchased the 4S. My old phone was an HTC Hero (no laughing). Anyway, when I purchased the phone they were unable to transfer nearly half my contacts to the 4S (which I find to be very poor form). I have entered some new contacts in manually and after I sync my phone to iTunes on my Windows PC, the new contacts sometimes disappear in my phone. An additional issue is that I am noticing duplicates of some names in my contact list. An example is that one person in my list is there 4 times. Two different entries are phone numbers only and two are phone numbers and email addresses. There is nothing that I have done that would have produced duplicates, and it's only some names and not others.
Help?
