Last Saturday, I bought and open box iPad (3rd gen.) 32 GB WiFi + 4G (AT&T) from Best Buy. A couple of days since buying it, I did the dead pixel test and noticed that it had a couple of dead pixels and dust specks under the screen. I took it to an Apple store today and received a brown box replacement. Based on the SN (DMPH) & production week (March, week 12) I gathered that my replacement is a refurbished unit. So, I decided to check on the warranty status and it says I have AppleCare+ although I never did actually purchase AppleCare+ with my original open box purchase or today with the warranty replacement. If someone returns an iPad, doesn't the AppleCare+ get canceled at the time of return? I expect that the AppleCare+ warranty that shows up on my replacement will disappear in a couple of days when systems are updated. Has anyone had any similar experiences? If so, did AppleCare+ get canceled eventually?
