This is such a bone-headed move on Samsung's part.
Sure, I've not yet been seconded to a country where I've stayed long enough to buy a local SIM. But like most of us in the tech business, that's something that might change tomorrow.

My S2 comes out of contract next month... I was planning to replace it with an S4. Ain't gonna happen now.
