Show me where in the court order (page number) that this backdoor is for every iPhone. Stop spreading false information.
If you think it is impossible for Apple to make a backdoor that only works on one iPhone, then explain how Apple can restrict apps I buy from working on someone else's iPhone.
"Stop spreading false information", coming from you of all people? It is absolutely you who is trying to bamboozle people here. The FBI chief himself has clearly stated that he has many more phones that he wants to crack in the same way. If you think he was lying, tell us about it.
Regarding your technical question, hoping that it isn't too complicated for you: The App Store transmits an application to your phone, together with a receipt. The receipt contains cryptographically signed information about the AppleID of the purchaser. The software on the phone only installs the software if the AppleID in the receipt agrees with the AppleID of the phone in question.
Installing firmware works in a completely different way. An iPhone accepts new firmware if the firmware is signed by Apple's signing key, making sure that the firmware comes from Apple and not from some random hacker. Since Apple makes all the firmware that it creates available to all phones, the existing software on the iPhone that installs firmware has no provisions whatsoever to check if that firmware is meant for this particular phone; it only checks that the firmware is signed by Apple.
Whether software can be installed or not is controlled by the software already on the phone. The software that installs apps has checks so the software can only be installed on one phone. The software that installs firmware has no such checks.

I hear you...but if apple was forced to make a next ios to have back door.....well.....
How can they be forced? The FBI tries to force them to do something because of a crime that has happened. When Apple releases a new iOS version, nobody who has committed a crime is in the possession of that iOS version yet.

I hope you're right. I dont discount that the FBI will try to argue that these engineers are impeding a national security investigation.
It's not up to the FBI to decide.
Read Richard Clarke's article on Ars technica, he asserts that the DOJ & the FBI do not have the backing of the rest of the US security community.
Absolutely. Worst case scenario: The NSA has techniques to break into the iPhones of terrorists. Maybe they found some clever trick to get around the "delete after ten incorrect PINs" feature. Obviously they wouldn't be telling anyone, because they would _want_ terrorists to store critical information on their iPhones. And now the FBI comes and forces Apple to unlock this phone, and all but the most stupid terrorists stop using iPhones and the NSA has lost that source of information.
(The NSA wouldn't tell the FBI either, because they _know_ that the FBI guys wouldn't be able to keep their mouths shut. If they broke into this phone with the help of the NSA, you would just _know_ that they would have to brag about it. Unlike the NSA which could do that kind of thing and _keep quiet about it_).
