How to COMPLETELY and PERMANENTLY DISABLE DATA

[adampeoples]

I promise I've searched for my answer before posting! I have an xv6800 on 3.57.605.1 ROM, 3.37.75 Radio.

I've already canceled my data plan with Vz so I'm not worried about how to avoid charges.

I want to COMPLETELY and PERMANENTLY delete data connection from my phone. As in, a hard reset would be required to get it back (if necessary). I'm fine with deleting registry keys or renaming files...whatever it takes! I dont text, or mms, or whatever. Wifi only!

I already know how to change my user name or delete the #777 connection in "connections" - none of these work. I also tried to delete HTC Guardian, and then deleted the Vz connection in "connections" but it still came back.

Every day, at random times, I get the following error:

Data Call Failure
Error: 11
PPP Connection Error

Something in my phone is trying to connect and I want it stopped!

Please. please. please. help. Verizon's response, is that I just have to deal with it, but this popup is driving me crazy.
