I'm thinking of buying a iPad Mini 16GB Cellular(I'm guessing it's 3G/LTE). Q1: Are all iPad Mini's the same 3G and LTE bands or are the 3G bands worldwide and LTE bands different? (Just like the iPhone 5) I travel to HK a lot and I'll need it for my next business trip, so I'm wondering if I can use the 3G/LTE in HK or not? (I'm buying a Canadian version, probably same as the US's) Q2: If I line up tomorrow morning, will I be able to pick up a 3G/LTE + Wifi 16GB model in store or are the stores only selling Wifi versions tomorrow? Thanks.
