Nokia has finally released the Blackberry connect client for Nokia E61 series. They will release the E60 and E70 versions shortly (they have a different screen resolution then E61).
E60/E70 might possibly work on N80 as well (keep fingers crossed), though Active Sync had some issues. (ActiveSync for E60/E61/E70 worked fine on these devices, but N80 had troubles opening messages).
I’ll report how does the BBConnect work
