Im fairly new here and created an account just to request help. i am running a iphone 4s on tmobile using the r-sim 7+ unlock on ios 6.1.2. is settings>about where it says carrier it will display not available. i cant seem to find the right carrier bundle for it because i dont even have any in the /system/library/carrier bundles. oddly enough, a week ago it had said that my carrier settings were updated and it said now said in settings/about/carrier vodafone nl. my curiosity had gotten the best of me and i had tried to change the carrier bundles not knowing that my phone didnt have any at all besides vodafones. is there a way i can put that vodafone nl carrier bundle back on? or even better maybe get the tmobile carrier bundle?
