---

1. Created a new Worklight project and application with the iPhone and Android environments
2. Added in wlCommonInit(): alert(WL.App.getDeviceLanguage());
3. Build All and Deploy, launch in device

In iOS
There are two settings related to language:

1. Settings.app >> General >> International >> Region Format

   I currently have Hebrew (Israel) selected.
   Launching the app shows me an alert with he.

   Changing to Gusii (Kenya) and re-launching the app then shows me gu, and so on for other region formats.

2. Settings.app >> General >> International >> Language

   Changes done here will take no effect.

In Android
There is only one setting related to language:

1. Settings >> Language and input

   I currently have עברית (Hebrew) selected.
   Launching the app shows me an alert with iw.

   Changing to English (United States) and re-launching the app then shows me en, and so on for other languages.
