title: What are the common practices to protect data on iPhone
body: <p>The client is concerned about safety of the data application uses and stores locally on device (e.g. they want to prevent reading our data files even on jailbroken iPhones). So I wonder - what are the possible ways to ensure data safety on iPhone?</p>
  
  <p>Edit: 
  I'm thinking about 2 ways of storing data - a bunch of xml files (maximum size - about 1MB) or sqlite database. I'm more inclined to the 2nd variant but still not sure</p>
