Grindr Xtra, the app with the world’s largest all male mobile location-based network, is now available for BlackBerry devices.  As of March 2011, BlackBerry devices share a nearly equal part of the market with iPhone and Android. Grindr is a revolutionary social networking tool that uses location-based and cellular technologies to allow users to locate like-minded gay, bi, or curious men nearby, view profiles and photos, and instantly connect via chat.

“BlackBerry users have been asking for Grindr since the very beginning, and we’ve been working hard to meet their needs,” says Joel Simkhai, founder and CEO of Grindr. “We are thrilled to now be able to offer Grindr Xtra to BlackBerry users and give them the fully-functional experience they’ve been asking for.” Users can download a free 7-day trial of Grindr Xtra from BlackBerry App World with full access to all features. After the trial period, users can continue using Grindr Xtra for $4.97 per month, with discounts available for longer subscriptions.
