This was probably the reason Nokia died. Symbian development, already cumbersome and app deployment required some such procedure. I remember there was an joint effort in a china based forum and many of us got a cert and a key for our phones. I was reading Nokia obituaries from its executives and the sorry state of Symbian development and app deployment was not considered as a cause. So here it, is young executives repeating a simplistic and destructive strategy. ibm, xerox, nokia and intel will be very proud.
