Generally not very good.  The coverage in Upstate NY is probably the worst
of all areas for T-Mobile.

Unless things have changed very recently, off the major thorofares,
you'll have nothing. I'll be going up that way Tuesday to escape the
hubub in NYC, so if it's changed, I'll post back.

We do have coverage now in all the "larger" (at least by local
standards) cities in Vermont, which is nice.
