ICS: Lock screen incorrect and Lock screen settings missing

[#1]

I have installed the ICS update for my ARC with SI number 1245-4552

and now I'm wondering that there is missing the menue "display -> lock screen settings" therefore I can't configure the Lock screen.

Also the Lock screen differs from ICS standard and Sony videos for demonstrating ICS features (e.g. ARC S with ICS).

On my Lock screen is on per upper part the clock (that's correct) but on the lower part is the key pad to fill in the password.

So I have none of the new features on the Lock screen available.

Also it is a bad behavior that on the Lock screen the key pad is allways available and it could happen that you type something what you don't want in case you have your phone in the hand or jacket or somewhere.

Has anybody an idea why the is no ICS style Lock screen and no settings?

Thx for your help.

OK, I'm convinced now

I couldn't know about that behaivior, because there seems to be no exact list of features of ICS for Xperia ARC. The manual is still the old one, also the manual within the phone.

As you know, the videos show functions what I can't know that these are exclusive for newer Xperia phones.

So I have to life with the available features.

Thanks all for help.
