Sony seems to make a big deal of updating FW with "supplied USB cables". My camera was bought used WITHOUT cables. Every firmware update with Fuji and Pentax was always done off the memory card, so this is a new thing to me, and fits in the "Who knew?" department. Clearly most folks received these cables with their cameras, but perhaps I'm not the only one in this category. I've read the Brian Smith article; I've read Sony's instructions; and I'd love to move from 3.1 to 3.2. Appreciate any advice on the cables. It's clearly not a rush... but gee... I do have a ton of USB cables lying around!!!
