title: How much RAM is there in an an iOS (Iphone/iPad/iPod Touch) Device?
body: <p>Different iPhones have different published memory 4GB, 8GB and 16GB. The touch can have 32GB. My understanding is this is the off-line memory (disk alike). </p>
  
  <p>How much actual fast ram is there in the device available for my Cocoa Application? </p>
  
  <p>Is there a preconfigured virtual amount?</p>
