Aha! I'm talking, because the new Nokia C-Series device like C6 comes with the old Symbian S60 v5. Ok, that is good, but there is another thing. Ok, you gave example with version 2.1 and 2.2 of Android and the iOS.

For example I have iPhone 3GS with iOS3 and Nokia N8 running Symbian^3. After half year iOS4 and Symbian ^4 are presented. The difference between iPhone and Nokia is that i can update my iPhone with iOS4, but for my Nokia there is no update. I must buy the new Nokia N10 for example. That's the problem. The possibility to upgrade your Nokia phone and stay tuned. The only Nokia phone that is able to be updated is Nokia N900. You now that, but that is my point.
