upgraded, previously "special offers" screensavers kindle4

Hi all,
i recently paid to remove "special offers" on a kindle4. :smack:
but of course the screensaver (letterpress printing letters) still says "Please connect wirelessly to download the latest Special Offers" all the time.

amazon help says there is no way to choose screensavers (maybe other than installing some $ screensaver pack).
anyone know how to get the authors screensaver like the "premium" kindles on there? i'm open to jailbreaking, etc
or a better screensaver? my sony reader had one that would loop through personal pictures. or maybe cover images of my installed books?

i've searched in here and elsewhere.

thanks!
