lol I was not aware that security hole. I have unfortunately no way to prove my honesty, excepted to provide the source of the full pdf file :
http://www.kk.org/cooltools/tf3-registered.pdf, from kevin kelly true film website :
http://www.kk.org/truefilms/. Btw the pdf was created in 2007 so I guess the author was not aware of the security hole...
Actually I'm indeed new, I tried to find the biggest forum of ipad readers since they would be the most likely to have encountered the same problem, I understand this is suspicious, if someone can help and require any kind of proof I can provide I'll gladly do it :-) (I dunno...taking a picture of my ipad opening the file ? pwah)
