As much as I support the blackouts, I have already contacted my representatives (though I think all the ones in the bay area are anti-SOPA). I think that earns me some Wikipedia time :). Turns out their blackout is just some CSS/JS added to the page (was probably the easiest way to implement it). This bookmarklet removes that (though it must be clicked on every page):

  javascript:(function(){$('#mw-sopaOverlay').hide();$('#mw-page-base, #mw-head-base, #content, #mw-head, #mw-panel, #footer').show();}())

Save that as a bookmark URL, click, and Wikipedia away on a non-mobile site.
