eBay is actively monitoring iPhone sale is fact. Within 2-3 weeks of July 11th launch, eBay actually updated guideline for iPhone specific sales. Apple is always watching, that itself has long track history. So for those guys to be selling massive quantity of iPhones, I don't see any other way but buying them legit. If they fell out of a truck, Apple will know. If they were ordered through some ficticious business, they will know.What do you mean eBay and Apple are "sensitive" with iPhone sales? Sensitive in what way? Like they would investigate how in the hell (are they going to edit that?) so many people are selling mass quantities of iPhones? Because that obviously hasn't happened.
And what do you mean the "strait forward approach"? You mean buying each one from a different person and amassing large quantities this way? I could see a few people taking this approach, but it seems unlikely that all sellers that have large quantities of iPhones would actually think this was worth the time requirement.
Just my thoughts anyway....
Buying them straight forward was applied in the beginning for several iPhone sellers on eBay. In fact, I have heard story of a guy who buys batch of iPhones at a margin from people who were exploiting loopholes to buy them at subsidized price in California, and to sell them oversea.
I am speculating like yourself, but I am pretty certain that Apple is monitoring those sellers. If they are not legit, they will be squashed sooner or later.
