When we came across contact management and synchronization service Soocial earlier this year, we said it made Plaxo look lame. The Holland-based startup is now waving the private beta phase goodbye and switching to public beta mode, which means you don’t have to wait any longer to try out the service.

In essence, Soocial enables you to sync contacts (and contacts only) between your computers, over 400 types of mobile phones and web applications like Gmail and Highrise. Later today, at the Under the Radar conference in San Francisco, Soocial will announce support for Outlook and Blackberry, which will evidently make the service far more appealing to business users.
