There is an app called X in my iPhone which can tell you whether or not you have installed other apps before in this iPhone.
Then I installed an app A into my iPhone, and app X tells me A has not been installed before.
Then I uninstalled app A and then reinstalled it, and app X tells me A has been installed before.
How does X know that A has been installed or not?
And how can I completely remove app A and let app X tells me A has not been installed?
I have jailbreaked my iPhone, is there any app can do that?
I am not quite sure if I understand what you are asking for. But if you are asking, how X is doing what you described, here is my guess:
If your iPhone is jailbreaked, every app can have full access to the file system. There is nothing on your phone the app can't find.
Under these circumstances, it is pretty easy to check if an app has already been installed:
Each app is installed in a path with a unique id. This id, however, changes with every reinstall (and maybe even if you update the app). What doesn't change is the bundle identifier in the app inside the app's info.plist. This means, if you see the same bundle identifier in two different folders over time, the app has been installed multiple times.
If app X is running in the background that is even easier: If the folder of app A is removed, the app has been uninstalled. As the phone is jailbreaked, app X can constantly check this.

The company I work for is busy in developing an enterprise app for both iOS and Android platform. The problem we've run into is that on the iOS app store, the name we need is already taken. So before we start experimenting with other options for the app name, we want to approach the developer and make him an offer for the name/or app, seeing as it seems like an inactive app with very low downloads.
Is this something worth looking at? Is this even a plausible option to explore?
Yes, there is an option to solve your problem.
You can buy that app by contacting the developer, and then you can change the entire setup.
The developer can transfer the app from his/her account to your company's/your account.

My applications update just entered the appstore. The problem is the application is crashing in iPhone 5, it doesn't start. I tested it in iPhone 4 and iPad and it is fine.
Does anyone have an idea why this is happening, or why the update was accepted in the store?
It doesn't crash when running from the xcode.
To reproduce your error install the previous version on your iPhone, then start the current version from xcode with debugging.
Sometimes such crashes happen for example when your previous version stored something in NSUserDefaults and your new version expects something different. Therefore it's very important to test the update scenario.
Apple does accept applications that crash but do not crash very often. I have experienced several of my apps still crashing have been accepted by Apple. May be they don't test it comprehensively or they ignore some crashes that happen only when a certain functionality is targeted i.e don't crash too often.

I have problem with deletion of application with grey background:
Longpress at app, selecting X mark and "Delete" option do nothing. Also have tried to do it through iTunes with no result. But I can remove all other applications on device. Can someone help me with it?
I'm using iPad mini with iOS 7.0.3.
UPDATE 1:
I incorrectly edited plist that goes with .ipa file and tryed to install this .ipa. That's why this situation occured.
Fix the issue with the plist, and push the app to the phone again. I've seen this issue with an invalid IPA, and I can't get around it until I update the app. But once I do, everything goes back to normal.
Make sure you are signing the app with your "Ad-Hoc" provisioning profile BOTH when you Archive it, AND when you validate and distribute it from Organizer.

An app will only work correctly if user setup the app's notification settings correctly in iOS settings.
Is it OK to bundle screenshots into the app itself, screenshots that depict the related screens of iPhone/etc iOS setup?
...or will Apple reject this if screenshots of the iOS settings app are not allowed in apps?
I don't find anything saying that this would be a problem at https://developer.apple.com/appstore/resources/approval/guidelines.html
But something guts tells me this could be disallowed.
According to App Store Review Guidelines
10.2 Apps that look similar to Apps bundled on the iPhone, including the App Store, iTunes Store, and iBookstore, will be rejected.
I guess you're worrying about that Apple will think your screenshots of the iOS Settings app makes your app look similar to the bundled Settings app?
In my opinion, if you wrap those screenshots nicely (e.g. with a frame, shadows etc) so users know that it's a screenshot, there's no problem with it.

my iPod works well as an development device.
But after I reset the iPod, my XCode doesnot recognize it any longer.
Its color turns yellow in organizer of XCode, instead of green dot before.
Please help. thanks!
Assuming that by "reset" you mean you restored the iPod, then all of your provisioning profiles, etc. will have been deleted from the device preventing Xcode from building to the device. To fix this, select the device in the Xcode organizer (where the yellow dot is) and click the button that says something to the effect of "Use for development".
At this point Xcode will prompt you for your developer credentials, check DDI symbols (and all that other fun stuff), and install the necessary profiles to the device.
It is probably missing your development profiles, make sure you reinstall them in organizer prior to attempting to use them for development
my question closed.
When I open Xcode 4.3, it can recognize my iPod as before.
Then I switch back to my Xcode 3.2.6, my iPod turn green again.
So strange. It works anyway. Thanks all!
