Log into your account at AppleStore, Blik. Then click on your SupportProfile. You should be amazed to find - as I just was (who knew?!

All the way back to my G5 desktop - 4 pages of products including all my iPod Nanos for my kids. All my computers and all my iDevices.
For some reason my iPhone 4 and 5S were missing from the list.. But I still have all my boxes and there's an Add Device button where you enter the serial number from the box and BAMM - it finds your device! My profile is now updated with 4.5 pages of stuff all the way back to 2003..
I must be the biggest techno geek out here.. But stuff like this gives me a "thrill up my leg"... If you will.. Lol!
Thanks to whoever first mentioned this little part of Apple's site!
So when my 6S ships - it should appear in that profile window? Even if I ordered it from ATT carrier app?
