Simplified directions for those who are sorta new to this and having trouble:
1. If you install CM7 after wiping (I flashed CM 7.0.3 to my Sprint CDMA Hero after wiping everything), you won't have Sprint VVM, so you can skip some of the steps in first post.
2. Download zip in first post to your computer, and extract there.
3. Download Titanium Backup to your phone.
4. Connect phone to computer (usb mode). Copy apk from extracted folder to sdcard root. Copy the 3 files from the extracted Titanium Backup folder on your computer to the sdcard/Titanium Backup folder.
5. Unplug phone, navigate to the apk in the sdcard root and install it. Don't run Sprint VVM yet (not sure it makes a difference, but I didn't run it until later).
6. Launch Titanium Backup - if you can see the Sprint VVM backup, click on it and restore - data only. If you can't see it in TB's list, reboot, relaunch TB and then look for Sprint VVM backup. When you find it, click on it, restore - data only.
7. Launch Sprint VVM. Compose a voice message to yourself (your phone number) to test send/receive.

I tried to update this apk and got a general failure message. I found a work around for anyone else having troubles.

You can actually do this from your phone. These instructions show you how to do this from your phone, not pc/mac. Instruction #1 assumes your are downloading to your phone, not your desktop, laptop or tablet:
1. Go here --------->http://xdaforums.com/attachment.php?attachmentid=1227489&d=1343494730 and download the .apk file
2. Go into Titanium and uninstall your existing T5.1.0.48
3. Using ASTRO file manager (available free in the play store) locate the file from your "downloads" folder and copy it.
4. While in ASTRO, back out to the root of your sd folder and paste T.5.3.0.32
5. Tap the file you just pasted and tap install.
That's it. No USB. No PC downloads. It worked for me first try so if you have troubles, please contact someone who has been here a while. I'm just a noob trying to help.
Good luck
how come CyanogenMod doesn't include this "fix" with the releases?
