(Newser) – Brothers Alexander, Marc and Oliver Samwer, founders of ring tone company Jamba, have just joined Microsoft and Hong Kong billionaire Li Ka Shing as major investors in US based social networking company Facebook. Though the Samwers' haven't disclosed the exact size of their investment, they told Der Spiegel  it was "significant," but smaller than Microsoft's $240 million.

The Samwers, who sold Jamba for $273 million in 2004, also recently invested in the German Facebook clone, StudiVZ; that sold last year for nearly $150 million, reports TechCrunch. Recently valued at $15 billion, Facebook continues to enjoy rapid growth, with an average of 200,000 new members joining the ranks of 60 million each day, 60% of whom now live outside the US.
