Had to get a new iphone 5 from apple store when home button quick working. They put in my old SIM card which quick working after about 8 hours, Sprint store put in new SIM and now with the replacement and card after reloading apps from icloud i can only locate the phone sporadiclly. Not sure why but seems like it can be located when the phone is awake but if "sleeping" all i get is an old location. Found that it had wrong number in settings>phone>my number and corrected that to no avail. All other settings match those on my iphone 4 which works perfectly. Anyone else had this problem, and what is the fix. I suspect it must be something on the Sprint network.
