One thing in symbian phones that is worst than other nokia phones is the behavior of keypad locking..
On my old n3320 I had a setup to answer on any key (unlocked) or just on the talk key when the phone was locked..
Seems like this is the default for nokia phones without symbian..
Now, my n6600 has the possibility to set "anykey answer" to On.. When setting this on, the phone will answer in anykey even when it's locked.. For a few times I was answering calls when picking the phone from my pocket!! Had to disable anykey answer...
I think this is just another detail in which a symbian lose for a common nokia phone..
Sad to say that..
