For what its worth, I just installed Gizmo to try and install something succesfully on my new second hand 770! It worked fine,i made a call through my cable modem to my landline.There was about a 2 second delay but the sound was perfect, what i dont get is where is the payment coming from and from who because i did not register any payment details,cc debitc or the likes!
Is it just a free trial then i'll need to submit credit cards to continue using it!
