This isn't terribly important--just random curiosity after seeing the endless discussions of various weeks on here. I got my iPod at Costco last week, and was initially disappointed that the serial number seemed to be a week 37 with a Macy Gray box(1A737...), but the version is 1.1.1 (3A110a) which seems to indicate a week 39. The screen is perfect and beautiful, so I am happy either way. So, what week/build is this? I know often Costco has their own batches of stuff, but that seemed unlikely with Apple.
