If you own any of these devices N8, E6, E7, X7, C7 and C6-01 the wait for Symbian Belle is finally over. Well, that is if you havent flashed any of the previously available leaks that were available in the forums. The stable version of Symbian Belle is available from Nokia via Nokia suite in select countries.
