Most of the files that setup the phone for a specific carrier are located in OEMOPERATORS in the OEM folder of the basekit. Remove all the files from that directory and replace them with ones for your carrier. I found it worked well to use the files from DogGuys Kitchen as he has them separated out in folders by carrier. Also there will be two files located in OEMAPPS that need to be removed, espt.espt and mxip_sprint_ppc_cert.provxml as they are not needed or come with the carrier files.

Hope that helps.
