digi will register it for you, whether it already been register when you received it i dont know.
no matter where you buy it from, the sale person need to do the register for you,
if you feel unsecure or didnt trust that person, or after a few days you phone still hasn't register,
you can register your self by emailing samsung, the method that post in the 1st page of this thread,
or you can PM one of our helpful member here by the name of fallenout to register it for you.
P/S: you cant register using samsung website.
hmm.... but the CS in dchat told me we hv to register ourself...
