There is a new leaked version of Ice Cream Sandwich for the HTC Rezound. This new build is version 3.14.605.10, and simply includes a few incremental fixes (SMS issue and data widget fix, and removes caller ID app). Still, speculation points to the possibility of a final version coming fairly soon, especially since HTC hinted that it might come in June or July. As always, be very cautious with leaked builds as they can leave your phone either bricked, or stuck on this version. Hit up the XDA source link below for a download link.
