I recently bought a 32GB iPad mini w/ Retina display for a pretty low price of about 200 USD. The guy who sold it to me said it was a Wi-Fi model but when I unboxed it I realised it also had cellular capabilities since it has the SIM tray and the antenna plastic cover. At first I was a little bit surprised but then I thought "Sweet! I got a retina mini 32GB + 4G" So here's the weird thing about it. When I go into the settings app there's no "Cellular data" tab/ menu like it's supposed to be. iTunes recognizes it as being a "iPad mini 2" and when I click on the serial number to switch to the type of product it says it's an "iPad 4,4" => this means it's a rMini Wi-fi only, right? Going on Apple's warranty checker webpage and inputing the serial number it says it's a Wi-Fi + Cellular model and I still have warranty till February 2016. Also, on the back it's written model number A1490 + the same serial number as in settings. So what's really happening?
