I need help erasing a "Home screen layout".

[IbelithLP]

You guys know that sometimes applications ask you if you would like to make it your homescreen.
I was wondering if there's a way where I could select the ones that have done that (that you see their layout on the "Home screen layout" list) and erase the layout in an efective way.

I tried by going to: "My device>Application Data>Home" and just erase it there, but it still appears as an option on my "Home screen layout" list(Start>Settings>Display>Home screen>Home screen layout").

Does anyone knows what should I do?

[Note: Hope I wrote this clearly enough so you guys can understand what I'm asking. If not, let me know what's unclear so I can get it fix. Thanks.]
