I got notified that it was available today while I'm at work with no wifi and I'm not even close to my data cap so I downloaded it over LTE. I'm not seeing any change in what my phone signal strength is and has been most of the day (floats between 3-4 bars) my wife is in the middle of downtown and called me on her way home and it sounded like absolute . No idea if it was her or me. She said I sounded fine to her. She has an iPhone 4S.
