Apple this afternoon revised holiday ordering and shipping deadlines for this year, as spotted by The Loop. For those looking to order customized Macs, you have until tomorrow, December 14, to place an order for your customized all-in-one system if you want to receive it by December 24, with free 2-3 day shipping. With custom engraved iPods you have until December 19 to receive it by the December 24 deadline.

And lastly, for off the shelf Macs and other Apple products you have until December 21 to receive them by Christmas Eve. Sadly, it doesn’t look like you’ll be able to get an iPhone 4S online before the holidays. Find all of the dates after the break:
