Playstation 3 3.55 kmeaw wireless keyboard

I own a ps3 3.55 kmeaw cfw with the latest multiman build.

I want to buy a wireless keyboard for the playstation 3 i can also use for the pc.
When i was searching for a playstation 3 keyboard wireless, i see the keyboard can used with at least firmware 3.60.

I am from holland
