Well, son, samsung's batteries are used in many phones I'm quite a few places other than the usa. So your point is moot.
heck, most samsung phones are released ELSEWHERE before coming to the us! Check google for what's going to be the phone of the year: the sgs2, and you'll see that it's been out for quite some time now in europe, yet it's not even in the us at all!
And not to be poking at an open wound, but you do make a lot of publicity for a company you basically say you have no interest in... It's okay though, just understand that some people view too much of the same information all the time as spam and start attacking the source.
JSYK, most likely if you do make a review of your experience using the said extended batteries right now, most people would just wait for another one. That's how much they associate you with the company.
