title: xml cache on iphone
body: <p>Could somebody suggest a technique or class library to read up on for XML Caching on the iphone?</p>
  
  <p>The biggest lag in my app is the XML being downloaded from the server. If a user views a screen the xml has to be downloaded and parsed and theres a wait of a few seconds. If they leave the screen and come back to it again they have to wait all over again which is kinda crappy.</p>
