But, you can ...
... in a country that has a 4G network.
Apple has already included a notice to customers who bought a new iPad in Australia that it is not compatible with any 4G networks that exist.
And just the same, you can take your car to Germany and drive on parts of the autobahn and reach well in excess of 230km/h.
I dont want to sound like a fanboi, but Apple are just advertising the devices capabilities, just like a car manufacturer asvertises that a car is capable of Xkm/h. It can do what it says, you just have to use it in the right environment - whether you happen to live in that environment is beside the point, you have to make sure you understand what you can do with any given device in your area. Otherwise, car manufacturers would have to advertise that a car is only capable of the maximum speed limit, which is just plain silly when it can do much more, just because you happen to live in an area which has enforced speed limits. How often do your hear of consumer outrage towards car manufacturers because their local roads are sign posted below the top speed of a car!?
So you buy an iPad that has 4G capabilities, but there are no 4G networks in your area? Thats not Apples fault. Blame your network operators. If you bought the device assuming you would get 4G speeds, thats your problem for not researching it properly. But lucky for these people, the Gov is there to protect them ... from their own stupidity.
Granted, these companies do use certain details as selling points for their wares, but unfortunately there is that percentage of the market that cant, wont, or dont educate themselves appropriately before making a purchase that inevitably leads to these kind of regulatory interventions, which really arent necessary and only serve to make it look like a company has done something dodgy when really they havent.
And they say the consumer is always right. I really loathe that saying...
