For what it's worth, I got 55 Mb/s on Spark 4G today at 12 pm. Not bad for "rush hour" as it were, and a huge improvement over the ~2 Mb/s that I used to get over 3G
Coverage doesn't reach as far as my house, but I don't really need it here anyway since I have my desktop and Wi-Fi.
I'm trying to to tell myself a 4G capable phone isn't worth it but you aren't helping
