When i was on itunes 9 using i phone version 4 and 4.01 everything was fine, as soon as the latest iphone firmware update happened it all went wrong. When i try to Sync outlook contacts or Calender it says would not do it and just freeze. So i followed advice and upgrade to itunes 10 and now i get a error saying " outlook sync client has stopped working" I looked into windows and here are the details of the error focusing on ntdll.dll
