      how much time will take this site for creating one certificate

    16. cyrilek November 18, 2010 at 11:12 pm #

      1) grasp your symbian firmly and hurl it against the closest wall
      2) then repeat the aplication signing process again
      3) restart your device
      4) if you find your app not working after this point, go to point 1)
      5) if your device won’t restart after some time, you are finally free from symbian and can move to android, blackburry and so on..

      ps: what ever happened you still must love Bakunin for his Jbak TaskMan
