PW3 Registration Help!!!!

Hey Guys

I have recently purchased a Kindle PW3 from dodgy dave accross the street and surprise surprise the device cannot be registered as its been reported lost or stolen albeit being brand new and sealed.

It's on the 5.7.4 fw and i've managed to jailbreak it. Is there anyway i can bypass the registration to use the full potential of the device (mainly just the WIkipedia bit)

Thanks in Advance,:thanks:
