The Nokia N86 8MP comes with a Symbian s60v3 with service pack II. Similar OS could be seen as in the Nokia E72 which I quite like it. The latest v31 firmware does not post any problem with the day to day usage of the mobile phone and certainly it did not crash during the first few days I am using it.
I am particularly happy with the fact that the speed of the firmware is very fast. In fact, the menu speed is faster than my old Nokia E72! Could you imagine it? Even the latest v500 firmware on the E71 is so much faster than the Nokia E72! I just don't understand why.
