Whrrl, the mobile social networking and discovery service from Pelago, has added support for a number of handsets, including the BlackBerry World 8830, several flavors of the Motorola RAZR and the Samsung M610. Support for the iPhone is coming soon, the company promised.

The free service, which already worked on the BlackBerry Pearl and Curve and the Nokia N95, combines social networking, local discovery and user-generated content with mapping and micro-blogging to help find something to do or a place to go based on user ratings and where their friends are. New enhancements even let users plot their friends' locations on the Whrrl map and drill down on the map to specific areas or criteria.

Whrrl is available to mobile users across the US, but it currently has "deep" location and event content for only a handful of major cities including Seattle, San Francisco, Los Angeles, Boston, Chicago, New York, Austin, Miami and a few others.
