There's no one standard definition of "4G". A myriad of differing technologies all claim to be 4G, which is why it's just about impossible for a vendor to produce a device compatible with every one worldwide. If "4G" had a solid definition, and everybody was using it, but iPad didn't support it, then it would be understandable.

While I agree theres no standard definition, theres a general agreement between all parties that LTE is "4G" and HSDPA+ is "3G" (or "3.5G" if you will).

To argue the semantics of what "3G" and "4G" really is only confuses customers even more - and thats exactly what Australia and the UK are trying to prevent.

Exactly. By stating that something is 4G compliant, when there is no real defined way of easily defining the term, then it's pretty misleading!
