My GPS isn't working properly anymore. Can someone help?
I have a jailbroken iPhone 5 on iOS 6.1. I'm not sure why, but something is wrong with my GPS. It never had this problem before. It's been going on for the past 2 months, but I didn't get a chance to look into it because of school. Whenever I go into any GPS application (Google Maps, Apple Maps), my location keeps moving around for a bit. It doesn't stay in place. Sometimes it gives me the wrong location. This hasn't happened before. If I leave it on for a while, it'll eventually get to a location that's close to where I am. When I'm driving, it'll sometimes show me in a building, not even on the road. When I'm driving, it updates maybe every 5 minutes, and even then it's wrong. I never had this problem before. It's been going on since November. I think it might have happened after I put my phone into airplane mode and then put it back out of airplane mode. I thought maybe it was a hardware issue, because this didn't happen on my old iPhone 4. I decided to test that theory out by restoring my iPod Touch with a backup of my iPhone 5. When I did that, my iPhone 4 started having the same problem. So, I'm guessing this has something to do with something installed on my iPhone 5. My iPhone 4 didn't have this problem until I restored it with my iPhone 5 backup. When I restored it like that, I put iOS 7 on my iPhone 4, and it wasn't jailbroken, so it didn't have Cydia or anything from Cydia installed on it. I tested to see if something from Cydia was causing the problem on my iPhone 5 by disabling all Cydia tweaks that run off of mobile substrate, but that didn't fix the problem either. At this point, I'm at a loss. I have no idea what to do. The only thing that I can think of to fix it is to restore my iPhone 5 to factory settings. I don't want to do that though because I would lose all my old messages, and I would have to manually download everything again, and I really don't want to do that. Does anyone have any advice on what I could do? I really need my GPS to start working properly again.
