Talking to my bud the Apple rep at my local Best Buy and whining about the slow laggy UI, he told me to try to reset my settings, see if it sped it up. I did, and it didn't. That aside, when I went to answer a text today, my little microphone button on the keyboard is missing. Don't know what I did to the settings, and I can't find it anywhere. Tried a reset, nada. iOS 7.0.2, iP5.
