What do you think will happen to all those 3Gs trade ins for the Iphone 4? I highly doubt they throw them out. You think the new Iphone 3gs 8gig will be made with faulty parts so Apple can fix it for you using the parts from the Iphone 3Gs 16gig and 32gig model? and charge you of course 
and maybe Apple can throw a deal on fixing your new Iphone 3Gs 8gig.. Ha ha
