Does the GPS system work okay on your iPhone 3GS? - 1

I recently got a second hand iPhone 3GS. However it seems to have great difficulty locking on to the GPS signal. The phone gets an approximate location quickly, which I assume is using assisted GPS, but it is very difficult to get a proper accurate GPS lock. I got a good lock if I stood in an empty field but lost it if I walked away. If I left the phone right at the windscreen on a car journey it locked on but if I moved the phone away from there, it lost it again.

So what I would like to know is, is this normal for the iPhone 3GS? Or is there something wrong with it and I should return it as it was sold as fully working?

How to control my OCD better?

Hi, I'm 14. I have really bad OCD. My room is completely organized. I write an everyday list of what I have to do for that entire day. Everything in my room is in alphabetical order as in my games and movies, etc. My desktop files and folders and icons are in alphabetical order and so as all my apps on my iPhone. All my books are in order at school from first period to last period. Everything has to be right before I leave that location. For example, I won't leave class until my work is done and if I do, I can't go on through the day. I constantly got to check my work to see if I did it right. And many many more problems. How can I control it better?
