The volume key is broken...So I went to Apple Store get a replacement iPad...I am so happy hat they replacement the new unit for me even I had a screen crack... My warranty period should run out on Jan.7, 2014. he work sheet stated that: Thank you for choosing AppleCare for the repair of your Apple Product. To ensure the highest level of quality and reliability, all work is performed by AppleCare certified technicians using genuine Apple parts. Additionally, all repairs are backed by Apples 90-day service limited warranty, or the original one-year limited warranty, whichever is longer. So that should give me warranty around to March. However, when I check on Apple support site with the new serial number, it still indicated my warranty ends on Jan.7, 2013... So what I am looking at? January or March?
