The message in the Bionic forum that I left you has the link ... http://www.mediafire.com/?44xx9n9f4lyl60s
... to download the .apk file directly.
I download it to a PC, transfer it to the phone, and then try to open it under Files. I then selected install.
It works on the Bionic and Droid 3. I don;t know if it works on the Droid 4 (because I don;t have a Droid 4).
If you visit the Verizon forum you will see a massive thread on the grad fathered unlimited data issue and it contains the statement from Verizon that they will not be curtailing the grandfathered unlimited data (not this round at least).
