Is that possible to run/launch application in background. I mean not making visible it to user?
For example by receiving local/push notification, even if user doesn't open(brings to foreground) an application, somehow open it in background, "hidden" for user?
Regards.
Short answer no, you can run programs in background on the iPhone like: audio players, navigation or voip clients.
Also if you app does not come to the forenground there is no way to receive any notifications(local or push).
The only applications that are allowed to do this are Newsstand applications in iOS 5.

I want a button to be enabled in my app only when call forwarding is active in the device, but am not able to find any solution on the net. Is there any way we can check from an app if call forwarding is active or not?
Nope. That's all locked down by Apple. If there is a way to detect it, it's only through a private API, which will cause your app to be rejected from the App Store if you use it.

I am interested to develope an app which will show quotes on the lock screen of my iPhone. I want app like following image.
I am trying to do it but not getting any idea.
Please help me so I can start working on it.
This is not possible, the SDK does not let you do this.
As #Toam pointed out, the SDK does not allow you to set the lock screen background. However, you can kinda-sorta get around this. If you're willing to play a little music, you can set your own images/text to the lock screen in playback mode. Details can be found here: https://stackoverflow.com/a/8387406/716216

I've been creating iPhone applications for the past couple of months, and one question has always crossed my mind: how does one go about creating an app like Instagram or some other application that lets users sign up and log in? I know how to do this with a website (SQL), but how do you do it on the iPhone? General answers are perfectly fine. Thanks!
The simplest approach: use UIWebView to wrap the website.
If you prefer using native UI, you can use JSON to communicate with the server for user login part.

I work on a ipod apps, and when I run it on a real device, my apps crash when the msgbox 20$% battery left. How I can fix that? I think this msgbox stop one of my thread(a timer), is it possible?
Does the same thing happen when the device receives a phone call, SMS, or push notification? If so, it's probably something in your app delegate’s -application:willResignActive: method. Check your code in there, or—better yet—update your question to include that code.

Same as the above question.
Probably the only way would be to send the work off to a server to do the work, and have that server send a Push message to the phone when it's complete. That would notify the user that the task has been completed, so they could then reopen the app and continue. But running something locally on the phone while the app is closed isn't allowed by the API.
If you're referring to background processes, the answer is currently no. This is a controversial issue with iPhone app dev at the moment as there is no way to perform background processing (afaik).
