Oh wow, glad I asked, and thanks for the detailed response, that the
Tmobile version was a target was completely off my radar, replicant has
so consistently targeted International versions of the Samsung phones.

I'm in the U.S. and a Tmobile user, so my occasional ebay
hedging/splurging has been badly misaimed.

That sounds great. Has Joey published any SGH-T889 images?

That's very cool, but having had the LTE bands of the N7105 pointed out
to me, my interest in the n7105 has just dramatically cooled. I don't
have one in hand yet. But barring ebay fraudsters I will soon and it's
now mostly a candidate for:

So imagine the situation is the same or worse for the SGH-T889? It
doesn't appear in forkbomb's midas matrix.
