title: How to target a specific iPhone version?
body: <p>I've got some code I want to only execute on the latest iPhone SDK (3.0), however I can't seem to figure out a way to target just 3.0 and ignore 2.2.1 etc. There is an ifdef statement, but it just seems to cover the entire iPhone:</p>
  
  <pre><code>#if TARGET_OS_IPHONE
  </code></pre>
  
  <p>Any help is appreciated.</p>
