HP 7 versions

when HP7 released, my hubby sent me a pdf copy of the so-called HP7... when i read it i find Harry different. when i got the chance to go to Festival Mall, i grabbed the chance of buying a 'real' Harry Potter and the Deathly Hallows hardbound copy book. when i saw the title on chapter 1, there i realize that the pdf copy my hubby gave me is 'fake'. maybe it is the 'hacked' version. of course, i continued reading the original version... and after i followed reading the hacked version. it has a very big difference... the Harry in the hacked version is a alter image of the original Harry and the way he killed Voldemort is different. but i like both... it's cool. =D
