I recently bought an iTouch2 for a friend of my sister's and appear to be having some problems with it. The card and SD card work fine on my sister's DS Lite, but not her friends. The only differences that I can see are: Sister's DS Lite is Black, the friends is Red The code on the white strip on my sister's DS Lite is UEH15506693, her friends is UEF28546952 Is there something obvious here that would indicate why it would work in one DS Lite and not the other? I'm hoping to try an iTouch1 in it in the next couple of days to check to see if that works. I also understand that the unit works ok with standard game cards.
