So, it seems like this thread has gone pretty much dead, and over the past year or so, my phone has gotten a pretty decent signal most of the places I go around town, including an LTE signal more often than not. I've been one of the unlucky ones who had never gotten a 4G signal at home, though... Until now! I went out of town last weekend, and noticed last night that my status bar indicated an LTE connection, instead of the usual weak EHRPD signal I've been stuck with at home for years. I did a speed test from my driveway just now, and while this isn't gonna knock anyone's socks off, I'm very happy with finally getting over 2Mbps download speeds without having to rely on my Wi-Fi!
It's nice to know that even though the Cleveland market's upgrades gave seemed to plateau over the last year, that they're still doing work and turning on new towers. Or at least one!
