title: Do I need to add armv6 support when limiting apps to iOS 4.0+?
body: <p>At the moment I'm compiling for both armv6 and armv7. I've also set the target iOS version as 4.0.</p>
  
  <p>Am I right in saying that all devices capable of running iOS 4.0+ are armv7, and thus I can stop compiling for armv6?</p>
  
  <p>Not a big deal, but it means that my app's binary will be quite a bit smaller if I can.</p>
