title: phonegap read and write json file
body: <p>I am looking to store a JSON file locally on IOS/Android in a Phonegap(Cordova) application.</p>
  
  <p>Basically, I retrieve a JSON file from the server ($.GETJSON) and I want to first store the JSON file and then retrieve and modify it.</p>
  
  <p>I've looked at FileWriter but I don't see a mimetype... the only example gives text files.</p>
  
  <p>Thanks in advance!</p>
