Hi, I am going on a trip to Eastern Europe soon and would like to know how I can turn off cellular data and any cellular connectivity entirely without sacrificing the phone's geotagging functionality. If I use Airplane mode, the GPS chip will be disabled and I can't geotag photos. If I don't turn it on and only turn off cellular data, I can still make voice calls and receive them. This is not what I want. I want to not be reachable via my number or make calls. I only want to use the phone as a camera with geotagging. I used to be able to do this on my old iPhone 4 which was jailbroken. I used SBSettings to turn off the Phone, 3G and EDGE toggles while leaving Location Services on. I want to do this on the iPhone 4S but sadly there isn't any option to turn off the phone functionality. Any ideas?
