How to prevent the OTA Jellybean update on Droid RAZR Maxx

Question

I have a Motorola Razr Maxx with ICS (4.0.2) on it. It went and downloaded the JellyBean upgrade, which I do not want to happen. Each hour the phone prompts me to upgrade. How can I keep this from happening? Can I delete the new files for JB and stop the hourly message? Thanks in advance.

(1) If you have root, you can use Titianium Backup, and uninstall "Device Management 3.0" (or some other version).

(2) OR, [also needs root], remove dmclient.apk, dmclient.odex, cmclient.apk, cmclient.odex from /system/app. Back-up these files first, in case you want to update in the future; you will need these.
