Foursquare promised a major turnout at the South by Southwest festival (SXSW) with a teaser and one of its first direct partnerships. The company is promising the 3.0 version of its app for Android and iOS users at the Austin gathering, possibly soon as March 11. What 3.0 would entail wasn't mentioned, but iPad support is a candidate, as is more advanced media sharing; 18 new badges are in store regardless of platform.
