I ordered a new 20" 2GHz iMac from the Apple store last Thursday, 5/5/05. My order said it's shipping on or before 5/12--I added the 400GB HD. Today, 5/11, the order status now says that my iMac configuration has been "replaced with new product." The only difference in the configuration of the "new" iMac on the order status screen is the addition of something called "Accessory Kit w/ Modem 065-5559." The old configuration said "No Modem Accessory Kit 065-5847." I can't find any info on this on the Apple website, and nothing comes up when I look up the part number. Can anybody tell me what this accessory kit is? Thanks.
