Yahoo’s location based service enabler FireEagle is entering it’s beta testing phase today with an official announcement at ETech. The new web site of the service is still featuring an invite form, just as the alpha version did, so it might still be a limited beta test, or maybe someone still has to flip the switch. We will know more once FireEagle lead developer Tom Coates climbs on the ETech stage for his Fire Eagle keynote, which should be around 9.30am PST.
