Found this method over on XDA. It will freeze all of the bloat on the Thunderbolt. As Adrynalyne noted earlier in the thread, it will come back with a data wipe. This IS NOT a permanent solution, rather something to get you by until we get a root method that does not wipe the phone.
YOU MUST HAVE THE SDK INSTALLED AND BE FAMILIAR WITH ADB! ATTEMPT THIS AT YOUR OWN RISK!!!!!
Download
psneuter and place it in your SDK\tools directory
Open a Command Prompt or Terminal window and navigate to the SDK\tools directory and enter the following commands:
adb push psneuter /data/local/tmp
adb shell
chmod 755 /data/local/tmp/psneuter
/data/local/tmp/psneuter
adb shell
