By e-mail, you should have received a copy of the JSQ, LLC Provisioning Profile with your device ID.  To install:

  1. Drag and Drop the Provisioning Profile on the iTunes icon.
  2. Download DianHua.zip
  3. Unzip the archive creating DianHua.app
  4. Drag and Drop DianHua.app on the iTunes icon.
  5. Connect your device and sync.

If everything works correctly, you should now have DianHua 1.2.1 on your iPhone or iPod touch.  Step 1 is only necessary the first time you install a BETA.  After that, you can start at step 2.
