How can I switch languages in hardware keyboard? I can't do this in my WP 7.5 OS.

In "Settings -> keyboard" I have selected two languages: 1) English (United States) and 2) Russian

but! I can't change language in hardware keyboard.

I press Fn + Sym but language is still English.

Now, if I need to type in Russian I need to slide off hw keyboard, and type Russian text in software keyboard - it's very uncomfortable. I want to type in Russian in hardware keyboard.

Any ideas about workarounds?

Thanks!
