I guess from a good news for Sprint Chicago users, I should have noted...this was during Lallapalooza weekend. And most my tests were on Michigan ave, Navy pier etc. Aka touristy areas. So there were thousands of people everywhere.
Like the above user said, I really hope the UofL area is upgraded soon. Nothing worse than tailgating at Papa Johns stadium and not being able to check scores from other games. My phone is pretty much unuseable on game days!
