@mindjigger: If you're talking about bypassing 3G restrictions, then meeeep, you're on your own (cf.
forum &
subforum guidelines) [also: don't].
Which is probably what you're talking about, since nothing's preventing you from browsing whatever the hell you want over WiFi in the browser.
If you were trying to repurpose the KindleStore Booklet, then that is way, way, way more involved than that, and no one has done it since the
K4, AFAIK.
