Called AT&T tech support due to horrible LTE speeds. They began troubleshooting and blamed the bad performance on IOS 6 running on my iPhone 5. She's like, "sir you are 2 versions behind and you need to upgrade your device ASAP to 8.2." I said I do not want bright colors and bright. She said older firmware is why I experience slow LTE speeds. I just found this insulting. I should run any version of IOS I choose too.
