utilities.js

var generateAttachment = function(uriString, fileName){
  var uristringparts = uriString.split(',');
  uristringparts[0] = "base64:" + fileName + "//";
  return uristringparts.join("");

Nice, this method is one of the best ones i have come across, most use the file system and the cache.
nicely done.
