title: What is the Windows Phone 7.1 start screen tile margins?
body: <p>I am trying to figure out what the default margins are for the WP7.1 start screen tiles, more specifically the exact positions of the top two tiles, from there I can figure out the rest. Also, I was wondering if setting these values explicitly when designing on a device with an aspect ratio of 480*800 would effect hwo this looked on a device with an aspect ratio of 340*480 (or whatever the new devices are)?</p>
  
  <p>In addition, if anyone knows, do these margins change in WP8 since more tile sizes will be introduced?</p>
