I have the same problem. My I777 is running the Shostock3, whenever I set "GSM Only", it always get back to the "WCDMA/GSM" after a reboot.
I don't want to change the ROM or kernel, so is there anyway to auto-run a script to active the "GSM Only" right after the phone start? I know a script should be put in init.d to be run at start but I don't know how to capture the script to switch the mobile network to "GSM Only".
