Okay DonB, I don't know what you do for a living but you have this android stuff dialed in. Driving home from work today I was thinking about all this and then it dawned on me that I didn't really delete the Sprint Voicemail. Earlier I was using Titanium and I was about to delete the Sprint voicemail app when I realized that it was telling me it was going to delete "Data". So in reality I only deleted the Voicemail data and not the entire program. You are probably correct that this program is securely nestled within the core of the Android/HTC/Sprint package. Truly amazing as this may be one of those things that you cannot get rid of. Unless it resides in it's own .apk somewhere and I can target that one program I'm very hesitant at this point to go after it. The interesting thing about deleting the data is it seems to have reverted back to the older version. A box came up after I rebooted the phone asking me if I wanted to personalize my voicemail like I did the first time months ago. Plus being it's not technically "working" as it's not personalized the sprint genie can't target me for upgrade as it doesn't know I'm using it. What do you think of that idea?
So here is where I am. I have the Google voice mail working and it's a very cool little program. I have a "Google phone number" that is free and actually works but I don't have to do anything about it as my original phone number works the voice mail just fine. So in reality I may have beaten Sprint to at least a draw on this one................
So to recap, I would say, if you don't want the voice to text sprint app you could go into Applications and delete the "DATA" and then it doesn't know who you are. Just leave the sprint voice mail application in the "unsetup state" and the monster "Mandatory Update" can't find you. You have effectively turned off the sprint voice mail that way and then you can install a third party like Google voice mail or Youmail or anything you want.
Give me you take on this DonB. I think this is whats going on and this may be the only fix to opt out of the Sprint program.................
