I bought a new iPad Air 2 today, for my grand mother. I didn't buy it in a store, but I bought it from someone who got it as a gift and didn't need it. The iPad is unopened, the plastic film over the box is also still there, so it was never touched. I entered the serial number on Apple's "Check Coverage" page, and I got this message here: When does the warranty start? Does it start at the point when I confirm the purchase? Also it says I should provide my date or purchase – I don't know that date. Is that a problem? Could anything be wrong with the device? Thank you very much. PS: It recognised the device as an iPad Air 2 WiFi + Cellular, which is what it is.
