Yahoo! now provides a new service which enables you to import all of your Facebook contacts details. Subsquently, this is a new development regardless of the applications that were granted access to users emails, as Facebook recently allowed.
It seems however, that facebook does not directly support this service but it may be part of a wider strategy to allow its users more flexibility. Nevertheless, this could however be a start of things to come, who knows very soon perhaps other sites like Twitter and Google Buzz may also this service.
Please feel free to add a comment to this post, thank you.
