looks fake to me, you have to complete a survey?? scams just use the tutorials in the hacking section with redsn0w sn0wbreeze or pwnage tool.. dont trust anything that is not directly from the devs themselves
Finally jailbroke 4.3.3 and I'm well chuffed! You can do so much more xD, here's a few screenshots
Done using redsn0w, added installous, crackolus, springboard and a few other bits, theme is BUUF, had to ssh to iPhone yo apply custom icons, super happy!
