can you help me with facebook?

I will answer your questions in order you have asked them and I'll try to be as clear as possible.

First of all, you cannot hide your profile completely. Your timeline banner and the snippet of your profile picture is by default public and you cannot change that setting. As long as your profile is there in Facebook, people will be able to see these two. What you can do is, hide your personal information. Go to your profile edit page (not from account setting, from timeline setting), you'll see the view option right beside your profile information, ex. your schooling, country you live in etc., click on the drop down arrow and change the view option to anything you want to.

When you post something from a phone, Facebook some times update things really slow. So it may happen, when you are posting in your wall, your news feed is updating it slowly. After you post something from your iPhone, try to check the news feed from a PC.

When you write something on your friends wall, the reason why others can see it because they are not meant to. If the person's wall you are posting in, has their updates protected from others, then others won't be able to see. it. They reason why you sometimes see other post like that may be because you were tagged in that post. But the bottom line this, every time you post on someone else wall, they are not going to appear on news feed.

Hope my answer helped.
