demon was kind enough to hold my hand through the process so I'll basically repost his instructions to me with a few modifications here and there but I take no credit for this info as it was others before me that came up with this info.
This assumes you are using the SPRINT Mogul PPC-6800, other 6800 models may vary:
1: Check your Windows\startup folder for "HTC_CM_Guardian.lnk", which is a shortcut to Windows\HTC_CM_Guardian.exe. If the shortcut exists delete it. If not then you probably have a newer Sprint ROM which doesn't have the shortcut to launch that application. It is still launching it in some other way however and I have not been able to figure it out from searching forums and the web. The general consensus is to replace the file with a dummy file that I've attached (extract from the zip). Download the attached file and replace "Windows\HTC_CM_Guardian.exe" with the dummy file which will prevent it from running.
NOTE: This file is what resets your Sprint connection to its default settings despite editing these settings. Disabling this file by deleting or replacing it is critical. You may need to use a program such as Resco File Explorer or another File Explorer utility to overwrite/delete/rename Read-Only or ROM files.
2: Rename the following files and folders:
Windows\iota.exe ---> windows\iotaOLD.exe
Windows\iotaconf.txt ---> windows\iotaconfgOLD.txt
Program Files\IOTA ---> Program Files\IOTAOLD
NOTE: renaming the IOTA folder is probably all that is needed however I found the files as well and renamed them for good measure and haven't had a problem.
3: Open your phone and enter ##778#, select "EDIT" and enter your unlock code.
4: Set the following values:
M.IP Settings:
MIP_MODE = Simple IP Only
M.IP Default Profile:
NAI =
yourtendigitphonenumber@mymetropcs.com
Home Address = 0.0.0.0 (just delete the values and save)
Primary HA Adress = 0.0.0.0 (just delete the values and save)
Secondary HA Address = 0.0.0.0 (just delete the values and save)
Security:
HDR AN AUTH User Id =
yourtendigitphonenumber@mymetropcs.com
PPP USER ID =
yourtendigitphonenumber@mymetropcs.com
PPP PASSWORD = metropcs
5: Goto Connections and delete any existing connections and setup a new one using the following settings:
Number to dail = #777
Username:
yourtendigitphonenumber@mymetropcs.com
Password: metropcs
Domain: (Leave Blank)
Select Proxy Settings and enter the following values:
wap.metropcs.net port:3128 (http)
wap.metropcs.net port:3128 (wap)
wap.metropcs.net port:443 (secure wap)
wap.metropcs.net port:3128 (socks)
6: Back in the "Connections" screen where you have two tabs at the bottom of the screen of "Tasks" and "Advanced", go to Advanced, click on "Select Networks" and select the name of the connection you just setup.
Example if you leave as Sprint then choose that one as your internet conection and do it for both settings.
