The iPhone has totally screwed AT&Ts LTE! It would usually take a few seconds to download an app under 5MB. It literally took me 48 seconds to download a 3.4MB app earlier tonight. I uninstalled it, got on my wifi and it downloaded in a second. Not only that but my Speedtest results show it too. I would average between 5-7Mbps down and around 2-3 up. Been running different tests most the day and I am lucky to hit 3Mbps down and 1 up. Most are around 2 down and under 1 up. Screw you iPhone!
