I figured out what is happening. The email addresses in my Google contacts are not tagged as "Work", "Home" or "Custom". One I tag them with one of these, they do sync to my phone. Problem is, most of them (hundreds) are coming from my Outlook client via a third-party sync program that does not provide a field mapping capability. The reason I am using the this method is that I have not been able to get the Microsoft Outlook (2007) to Hotmail sync tool to work. So, any guidance on this appreciated!
