I know eastern Oregon was mentioned as getting LTE turned on soon, but nothing was said about central Oregon, Bend specifically. FWIW, I was in the one and only corp store in Bend this morning getting a sim changeout and asked and was told they are currently in testing mode in Bend and are scheduled to turn on in a week or so or possibly August at the latest. This is great news for us here. Several other cities in more western Oregon have already been lit up so I'm hopeful that this timetable will come to be.
Side note: getting a fresh sim card has really helped my 3G data connection from dropping. I'm going to leave my LTE enabled on my Maxx and watch for the grand opening.
