Contact list field data isn't appearing on my computer
You can only synchronize the data in a custom contact list field with a text field in the email application on your computer.
For example, you can't add a contact's birthday to a custom contact list field on your BlackBerry smartphone and
synchronize it with the email application on your computer, because the birthday field is a date field in the email
application on your computer.
