For whatever reason they have decided Nokia has put out in a recent financial statement that they will not be speaking of and possibly not releasing any thing on Symbian ^3 or Symbian ^4. There are so many possible reasons for this action by Nokia, but one that we can safely assume is that it is due to their current financial issues within the company. As we have heard before Nokia was already suffering major cuts even within their largest retail country, India. Another reason for this could be that since their sales are suffering and it is possibly due to lack of shifting from Symbian to a more popular OS like Android. Whatever it may be all that we know is there will be no further news on Symbian ^3 or Symbian ^4.
