i have a problem downloading these 3 applications onto my curve 3g 9300
first of all .. the bb app world is not provided in my country and dont know whats the reason
from 2 weeks or sth i download another software from google which is os6 , i didnt like it and downloaded again the os5 which is the original .. then i deleted facebook and youtube apps from my mobile and when i go to bb desktop software ( updated ) i dont find neither facebook nor youtube apps
so how do i download them directly from my mobile ?
thanks in advance
