Yeah, you're telling me, brother. We've got all kinds of "speed upgrades" and "capacity upgrades" in Madison, but I haven't had an inkling of LTE signal at all....not that I'm expecting to be able to access it, but seriously man. I live directly across the street from one of their biggest towers in the area so I'd assume it would be first-ish on the list. You know, the only place to catch WiMax in Madison (which is/was never launched here) was a fleeting amount of signal on a dinky tower over near West Towne Mall, near Woodman's. So who knows, maybe that'll be the first tower.
The story I've gotten about Madison from a Sprint guy in KC that I trust was that this whole network was 3rd partied for Sprint for many years and then recently (like 5 years ago) they bought back all the towers and started running it again. They know it is under powered for the population and they are working on it. I'm really, really, really holding out here with Sprint. Have 5 lines invested in them in multiple cities. Really hope they do something here soon. I've been patient.
