I have tried doing that, but still, when I opened the pdf file as html, and then I checked the page-source, the link was present as simple text and not hyperlink, so I am quite confused over this ! Anyways here's the pdf I am talking about: www.cs.cmu.edu/~prs/wireless09/handouts/L1-Introduction.pdf and my blog is linked as "http://bloggerstop.net/2008/01/first-mobile-phone-first-fully.html"
