title: How to accommodate for the iPhone 4 screen resolution?
body: <p>According to <a href="http://www.apple.com/iphone/specs.html" rel="nofollow noreferrer">Apple</a>, the iPhone 4 has a new and better screen resolution:</p>
  
  <blockquote>
    <p>3.5-inch (diagonal) widescreen Multi-Touch display<br>
    960-by-640-pixel resolution at 326 ppi</p>
  </blockquote>
  
  <p>This little detail affects our apps in a heavy way. Most of the demo apps on the net have one thing in common: They position views in the believe that the screen has a fixed size of 320 x 480 pixels. So what most (if not all) developers do is: they designed everything in such a way, that a touchable area is (for example) 50 x 50 pixels big. Just enough to tap it. Things have been positioned relative to the upper left, to reach a specific position on screen - let's say the center, or somewhere at the bottom.</p>
  
  <p>When we develop high-resolution apps, they probably won't work on older devices. And if they do, they would suffer a lot from 4-times the size of any image, having to scale them down in memory.</p>
