Need to delete Sprint dialer and IOTA settings

[Etrnlwanderer]

I'm running the Sprint Leaked ROM on a network in India. I've enabled my network dialer for the phone and calls can be made just about perfectly with the phone. The only hitch I'm facing is that when I try to connect to the Net, the default Sprint dialer takes precedence over my network dialers and isn't able to connect. It dials the default Sprint PCS dialer and shows "Trying to enable Vision Services" in the Data Provisioning notification and then it disconnects showing an Error :1012, Unable to prepare Vision service.
How do I delete the default Sprint settings completely from the "Select Networks" settings in the Advanced tab of Connections???
Even if I manually delete the Sprint PCS dialer from the list, it keeps coming back.
I would also like to know if there is a method to manually delete all IOTA references from the registry.

Thanks in advance for all help rendered
