Great news coming from Vietnam. Nokia Vietnam has shown on its website that Symbian Belle release date is 08/02/2012. It is in sync with what we predicted earlier that Symbian Belle will be available in next 1- 2 weeks. But now we have a date to look forward to. As a global release is confirmed by Nokia, it seems this date can be valid for other regions as well. Check the link below for details.
