Is this a user generated location map? There doesn't seem to be any consistant pattern with the colors of the pushpins. Plus there are many locations missing especially Verizon locations.
What this consist of is new LTE Markets that was just re-leased by Verizon an other companies.. An not the one's that are already in existence. And i assume as newer ones come out it will update them.
Update: if you click on the Orange Balloon it will pop up a square Box showing when a new Market Came online
