Nokia dropped the N78-3 like a hot rock. The last update for it in the US was 21.002 (10-03-09). Elsewhere in the world 30.0.015 was released to take care of the issues not addressed by and those issues created by 21.0. That was 13 months ago. The phone works okay as long as you don't run into one of the unfixed issues. The phone had been released five months when Nokiausa stopped selling it and less than a year when the last update arrived. That is what "not supported" looks like. Nokia is continuing to support the N900 by updating Maemo now and releasing Meego in the future. The future looks bright for the Type RX-51, not the "dropped like a hot rock" treatment at all.
