I was searching Cinco De Mayo on my wikipedia app on my iphone. There are only 4 words listed under the "History" section..."shut the f up". But i searched on my HP computer using Win 7 xp - the history section is complete and several paragraphs. So there must be some hack on the iphone app that allows someone to edit that.
