I don't think you understand burden of proof. The burden of actually buying the phone and demonstrating that to the audience is yours, not mine. Want my PO Box address to mail a GSM iPhone 4 to?
The change doesn't have to be in the phone, that was an illogical assumption on your behalf. Adding a case changes the conditions in which the phone operates thus working around the problem. Furthermore, analogies are fallacious in natured due to inferring from the particular to the particular, so refrain from using them again in arguments with me. Not that any of this matters, I have proven beyond reason that there are issues with the iPhone 4's antenna gate, you are yet to contest any of the evidence that I have provided so far, so answer all the questions that I asked earlier objectively!
