IPhone 4S showing wrong location

I live in a place called Ashington, my iPhone 4S is showing I'm in a place called Newbiggin, like when I post a status on Facebook it says in Newbiggin, I'm not I'm in Ashington, from Ashington to Newbiggin is only like 3.5miles but its confusing my Facebook friends, please someone help me, I need it to be the correct location

if possible could people explain in step by step how to fix the problem

Try typing in your address and see if it shows as a location. If not, you can't really create it with Facebook and have to use your nearest location. Kind of dumb. With Instagram, you can title you location properly and actually have it pinpointed exactly where you are. Sorry about that.

My ip4 doin well… Try this hope your will be well…
1. Close all open applications.
2. Power cycle the phone.

Seemed to clear up the issue. From what I found in reading different article online - when you power cycle the phone, it clears all cached location data.
OR
Go to your location services. On the bottom is system services. Go in there and turn off setting time zone.
Then go back and set your time zone correctly. Leave auto set time set to on
Now go back and turn on setting time zone under location services.
