For those of you who are interested, Verizon finally has LTE in the southwestern portion of Maine (Portland, Biddeford/Saco/Old Orchard Beach, and Kennebunk/Kennebunkport). I have seen a few posts on the DSLR VZW forum wondering when 4G LTE is going to arrive in Maine and it is finally here. I live in Mass but travel to Maine quite a bit as Grandma lives in Biddeford.
I did a few speed tests using my Jetpack 890L and here is what I got in the Biddeford area. It actually seems faster than Grandma's cable modem connection.
