ATT Rep now available
Perhaps Seattle has some ATT LTE. I think I've heard there's a small pocket of ATT LTE around the Microsoft campus. But anywhere else, nope just the faux 4G.
I checked my systems and it is showing that Seattle area is planned for 09/20/2012 to have LTE, now the date doesn't mean that it will actually be there on that date, could be a little before or a little after.
As for your actual area, I can't state. Either PM me or just post on this forum again, and I will be happy to check your exact area.
For any reps who read this and doubt check Geolink
