Mitchell McKenna shared an idea in Magma "Import Contacts From Twitter, Facebook, or G-mail"

As with joining any new social network, it's important to figure out which of your friends are already on there. It would be nice to have the ability to import your contacts from other social networks. Often these networks provide an API to access their contact lists, and many other networks (such as Friendfeed, LinkedIn, etc.) have a similar feature to import contacts from Twitter, Facebook, Gmail, etc.

As well, support for Hotmail, Yahoo, etc could come later.
