My apologies, and thanks very much for the correction. On another note, has there ever been any custom OSes for the late 2000s era Nokia dumb phones, built by some stubborn hackers? Or some modification software to hand-tailor the Series 40 iterations, e.g remove features the user doesn't need. That would make these phones fun to mess with.
