My iPhone 4 USB cable is starting to crack and in need of replacement, so I called AppleCare to get them to ship me out a new one. Something odd came up though - as the CSR was trying to set up the replacement request, he couldn't find the proper USB cable in the system. He put me on hold and then came back and said that he looked up the part number in his "other system" and that it is listed as being phased out, so he had to go onto the Apple Store and do a "sales order" for me in order to ship me one from the remaining Apple Store stock. So... I just thought that was strange... Apple's systems showing standard iPhone 4 USB cables as being "phased out"... perhaps a revised USB cable is on the horizon?
