The article described tests that are not statistically valid. I made no allegations regarding any testing done by Apple.
As for your questions as to Apple's policies, such discussions are forbidden by the terms of service here.
If you wish to make allegations of fraud against Apple, I suggest you consult an attorney. Such discussions are also prohibited here by the terms of service.
Nowhere does Apple claim that the iPhone will function in ANY way on a carrier that is not supported. It may, however, if it does not, it's between you and the carrier you have chosen to use. They have detailed quite clearly which carriers have supported LTE networks. http://support.apple.com/kb/ht1937
If the carrier you choose to use is not on that list, then your complaint is with them, not with Apple. Apple has provided a path for carriers to become supported. If you work for such a carrier, then I suggest you take it up with your superiors if you're not happy about it.
