Just installed the new firmware (it was not officially released by Nokia yet).
I got a few days to test it and it lloks to be really good, a lot better than the buggy 4.09.1.
Handshake intro screen fixed (sound+video ok, does not skip anymore)
A bit faster overall but not much. depends on your mmc size i believe.
No more sudden reboots and shutdowns, very much stable.
Better battery life, I get approx 1 day more in standby.
All apps work as before all NGAGE work no changes here
BT ringing-routing works
