FWIW, I was down at Lollapalooza over the weekend, Sprint service was pretty good most of the time. Texts went through quickly for the most part, data was usable. I was on B25 most of the time, but got on 26 and 41 occasionally. Heard more complaints from my friends with other carriers than issues I had with sprint during the weekend. Not sure if they brought in temporary towers for the event or not... But I'm thinking it'll still get better with time up here.
