Hi, Chris.
I did some research and found that your answers are not completely accurate.
The T-mobile contract-free iPhone is already being sold, but it will take 7-10 business days to ship. And, as confirmed by Apple Specialists and also by people who have already bought it, it is factory unlocked.
Yes, there is a contract free T-Mobile phone, but it is not "the" unlocked phone which Apple will begin to sell usually 2 months or so from the release date. So my answer to that question is accurate. I specifically identified the T-Mobile phone, and a search of the forum would yield some responses identifying its inability to work in some locations. And again, it has to be the T-Mobile phone sold at the Apple store, not T-Mobile.

Regarding French LTE bands, they use 800, 1800 and 2600MHz, all of those supported by the iPhone 6.
While that statement is accurate, see Lawrence's response regarding how it works.

And finally, about the warranty, that is also something that should be checked country by country. Although Apple says its warranty won't cover products purchased abroad, some countries' laws require manufacturers to provided services under warranty to phones no matter where they were purchased. For example, since Apple has a branch in Brazil, justice here has repeatedly ruled in favor of customers  who needed service on iPhones purchased in other countries.
While that may be an example, the overall warranty statement by Apple is that warrant is specific to the country of purchase for the reasons that Lawrence states. Certain devices cannot be found in certain countries. Should I travel to Brazil and have a problem with my phone, they would have a very difficult time replacing a locked AT&T device. They would not have that stock.
