title: iOS x.x adoption rate
body: <p>I'm curious what percent of iOS users are running with version of the operating system. I'd really like to cut my new app as 6.0+ but also don't want to screw over the 5.x folk.</p>
  
  <p>I did a lot of Googling, but it mainly turns up tech articles, that either aren't current or not informative enough (all about iOS 6.1). </p>
  
  <p>Is there a known source for this that is updated in real(ish) time? I can't seem to find one. </p>
