Symbian Anna is the new version of Symbian^3 that adds a couple of new features to the platform such as the long waited full QWERTY touch keyboard in portrait mode. The Nokia X7 and the Nokia E6 come with Anna out-of-the box but if you own an N8, E7, C7 and C6-01, you will have to wait until the end of August to update.
Nokia tweeted a confirmation of what it already made public at the end of June. Plans are for everyone to be able to update to Anna by the end of August. By everyone we mean (and we think Nokia also means) owners of N8, E7, C7 and C6-01. These phones will ship with Anna starting July and users who already got the phones will have an update to Anna ready by the end of next month.
