- Connect your 4S with iFunbox or any other iPhone file manager to PC
- Go to ar/wireless/Library then delete file carrier_310VZW_20404_11.2.plist
- Go to /System/Library/Carrier Bundle/iPhone delete folder Zeppelin_US.bundle
- Delete your sim card carrier bundle in the same folder ( if your iphone is Sprint so delete folder sprint_bundle - NOTE. in some phone this folder does not exist, just skip this step)
It`s done, now your CDMA modem does not have PRL (preferred roaming list file) and will not be able to search and register on CDMA network.
Program your gevey with correct settings and enjoy your unlocked iPhone 4S.
I have personally tested 2 Sprint 4S in US and got them unlocked with V13 update.
NOTE: IM NOT RESPONSIBLE FOR ANY DAMAGE CAUSED.SO DO IT ONLY IF U SURE U GOT ENUFF SKILLS.
