Clear Task bar and Buttom ?

[dkotoric]

I really like how on windows mobile 6.5 the Top task bar and buttom is clear. Is there any way to get this accomplished on windows mobile 6.1. Like what I want is to show my background throught the entire screen and to remove the top and buttom like shown in the first 2 pictures below. Also is there any way to have unluck your phone option like in Windows mobile 6.5.
