Does the hack above really work? Can you just download CS3 from Adobe and use this hack?

not sure, but I don't doubt it, there are tons of apps with simple ways around it.

For whatever reason it reminded me of back in the day MS used to use a 10 digit serial number for a lot of their stuff. the serial number was broken up into a 3 digit field and a 7 digit field. The whole algorithm to verify the serial was to throw away the 3 digit field and then sum each digit in the 7 digit field and then divide it by 7, if there was no remainder then it was accepted as a valid serial. That's why there were tons of serials floating around that were all XXX-1111111 where XXX was any random three digit number
