Can I just point out that Apple clearly believes that HSPA+ does not fall under the 4G umbrella. They clearly accept that 4G access is not available outside of AT&T and Verizon (and the three Canadian carriers) on all their iPad pages worldwide...
By their own definition, Apple accepts that 4G access is not available to those purchasing an iPad which is 'WiFi + 4G' in Australia.
So to all those yakking on about how the large HSPA+ networks in Australia technically mean that Apple does off 4G -- you're wrong.
Apple should not being marketing this product as 4G, then taking that entire element back in their fine print. By their own admission, 4G is not supported in Australia, so therefore saying loud and clear that it is is misleading and deceptive.
Go for it ACCC.
Then the ACCC should take this up with the ITU.
