title: Running iOS SDK built in arm7 on arm7s
body: <p>I have an SDK to achieve some special stream of video but I've got only the binary of this, I think this was built for arm7.<br>
  I have an app built with this library and it runs great on iPhone 4, 4s and iPad 2 but when building for iPad 4th generation with an arm7s xcode shows lots of errors about files being ignored.<br>
  I'm pretty sure it's the architecture cause changing the build architecture the errors appear and disappear.<br>
  Is there any way to make this work? I mean build for new architectures having only binaries files of the old one?</p>
