i18n solution if cross platform apps required

app.js

// you could create a simple function to check the platform and deploy default lang otherwise use strings.xml

// Call the function with LS("key); instead of L("key");

// You will need to create a switch for each key in the function, but this is temporary

function LS(string) {"use strict";
  var str;
	if (Ti.Platform.name === 'blackberry') {
		Ti.API.log('warn', 'Blackberry detected, string manipulation');
		switch(string) {
			case "myKey1" :
				str = "A Title";
				break;
			case "mykey2" :
				str = "Some Default Label Text";
				break;
		}

	} else {
		str = L(string);
	}
	return str;
}
