Re: Why?
"so as the article notes it needs a T-Mobile-specific firmware for it to work."
It's actually not true as it's still not more than a couple secure extra packages installed - the keyword is "secure" so you cannot install yourself (in the early years I used to but then few years ago they made it much harder and subsequently they bumped up their coverage in NYC to the current level of greatness so I don't care anymore.)
