I have a new PS3, (actually my son). I have the serial number. Is there any way to find serial number of the remote that came with the PS3? My son claims his friend switched his old PS3 remote with my son's new one, only a week old. Is there any way I can find serial number to verify if I already threw out the box? The only thing I can see is the one that the kid "claims" is his, has a visible pressure mark on the start button, similar to the pressure marks the computer keys get that are used most frequently. I don't think my son's brand new remote could have that mark because it is less than one week old? Any suggestions? My son said the one the kid pawned off on him is already sticking (buttons) and my son's was not sticking? Help? Had a big scene with parents and they did not understand why it even mattered?
