Location settings for the facebook app in iphone?

When location services is turned on and you chatted with someone through facebook mobile, there's something like in grey text below the message "Sent from ___" as seen on the desktop version of Facebook. I'm having problems with this because the location it states there's way too far from the vicinity I'm in. Around 8 kilometers away. It's even in a different city. It's weird because there's a locality much closer to where I'm, not even 2 kilometers away. Is there a way I can change this?

Added (1). I've done the Skyhook thing a long time ago. I just want to correct the wrong location being stated, even though the Skyhook thing has already been done

Is it a iPhone tracking app?

So my friends boyfriend has gone… A little crazy perhaps. The other day she went the park with some friends and she kept ignoring his text/calls and when she got home she called him and said "sorry I was asleep" and he was all like "no, you're a *** liar cause I know you we're at a park" he never would tell her how he knew, but he did.
She thinks he has a tracking device on her phone or whatever or like an app. But she doesn't have any apps like that on her phone so she doesn't know how it would work?
Does anyone know what type of app she might have or what could be going on? I don't know if its important but she has an iPhone…

SIM card failure in iPhone 4S? From water damage?

Three days ago, a water bottle spilled into my bag and around my iPhone. The sound stopped working for a while but after I dried the phone with a hair dryer and put it in rice for a while, it went back to normal. It was fine for a few days. But this morning I woke up to find there was a notification that the SIM card had failed. Now I have no service. I think it's because the card was damaged but I don't know. How do I fix this problem? Do I restore the phone or do I need an entirely new SIM card?
