Contact entities have the following property:
imList: Specifies a list of the contactís instant messaging addresses.

I'm able to retrieve ALL contact properties (ex: phone numbers, organization info, contact notes, etc.) except for this imList property (it always comes back null).

1/ Create a contact using WebAccess
2/ Specify an Instant Messaging address
3/ Save the contact
4/ Retrieve the contact using getItemsRequest

I tried different views for getItemsRequest and the imList property is never returned:
1/ null
2/ default
3/ default imList

Is this a known bug?
