title: How do you change the app store's large icon on iTunes connect?
body: <p>I need to change the large app icon (512x512) for app store. I can't find how to to this through iTunes Connect. I's possible change the app screenshots though. I read the <a href="http://www.google.si/url?sa=t&amp;source=web&amp;cd=1&amp;ved=0CBUQFjAA&amp;url=https%3A%2F%2Fitunesconnect.apple.com%2Fdocs%2FiTunesConnect_DeveloperGuide.pdf&amp;rct=j&amp;q=itunes%20connect%20pdf&amp;ei=zsRgTv2xLsz1-gbg58Ef&amp;usg=AFQjCNHIe5z2hgZca_u0YEjm4U3sU_3b-g&amp;sig2=hil4RoykewZIZMMDwLN0kA">iTunes manual (page 97)</a> and it says that it can be done but I only have the "choose file" button for screenshots, not for the large icon.</p>
  
  <p>I am also confused because the same manual says on on page 99 that edit-ablity of the large icon is locked.</p>
  
  <p>What am I missing?</p>
