I'm not sure what all the fuss is about, the cell towers have to know roughly where you are in order to route your calls, sms messages and even to make your phone ring. The only difference I can see is that this info is now being stored on your phone, why is that a problem? We are all carrying round this bit of grey matter which is doing the exact same thing.
It is still just possible to not be tracked if you follow this advice.
Don't use a credit card, and don't use a cell phone, don't even carry one, and don't use social networking of any kind, don't use any store based loyalty cards, don't have or use a bank account, buy everything with cash, work strictly cash in hand for someone who doesn't want or need to see your national insurance number or social security number, don't use or own a car use public transport instead, never fly anywhere, don't have any subscription based TV or radio services in fact don't have any subscription services such as land line phone or internet, Don't respond to any mail that drops through your door. In fact it might be best to be homeless or sleep in a tent.
Get Real people, just about everything we do in modern life allows us to be tracked in some way or other, why should a cache file used to help the phone and its application know roughly where it is make any difference?
If you are not breaking the law then you have nothing to hide. If you are breaking the law then be worried, be worried about the fact that we are all leaving DNA trails behind us all the time in the form of skin particulates and hairs. Be very worried because big brother is watching and recording, but also know that if you are not in the spotlight then he doesn't care.
