About carrier lock

I have an iPhone 4 and it is from Japan. It's contract is expired but it's still locked and I am not able to use my carrier. So now what should I do to unlock it.

Provide AppleCare with either the iPhones IMEI or serial # and ask if they can tell you who the iPhone is locked to. Follow the link below for the number in your country:

If the carrier is au or Softbank then you won't be able to unlock the iPhone as it shows in the article below:

How to unlock a carrier locked iPad 1?

I have a iPad that was bought on contract on Orange.
I have a 3 sim and when I try it, I get a message in iTunes "The Sim card inserted in this iPad does not appear to be supported"
I am guessing it is carrier locked, I have found a few people on the Internet that have had the issue with the iPad 2, but not sure about the iPad 1.
Anyway, how would I go about getting it unlocked?

If the iPad is locked to Orange, only they can unlock it, so you'll need to contact Orange customer service.
Regards.

Unlock carrier locked iPhone(perhaps refurbished

Hello,
I've purchased a used iPhone 3GS 16gb 2 years ago.
The person selling the phone said that it was carrier locked to 3 in Denmark but it turned out that it was possible to use it with 3 in Sweden( where I live) as well. However when restoring it I need to start it up with a pre-paid 3 sim-card from Denmark, after that the Swedish one works fine.
Since the 2 year time period for unlocking must have expired I now thought about unlocking it, however when I contacted 3 in Denmark they couldn't find the IMEI number in their system...
So my question is could this be a refurbished phone? If so how can you then unlock it if the carrier can't find the IMEI number in their systems?

That may be because you have a Swedish sim in the iPhone ( if I followed your changes correctly )
All carriers need to see the iPhone active on their system before they can unlock
Must admit I haven't come across any time limit for unlocking
put the Danish sim in use it in or by the Danish mainland and they will then probably see it

I have iphone 4s from japan which is a carrier locked (kddi ) it has ios 5.1.1 and now i want to upgrade to ios 6.Can i do the software update or it will cause any harm???

If you have a Japanese iPhone and are using it with any carrier other than Softbank or AU, then it was hacked, since as the others have said neither of those carriers unlock iPhones. Therefore if you upgrade iOS or restore your iPhone, it will lock back to the original carrier and be unusuable with your current cell provider.
We cannot help you with jailbroken iPhones. You'll have to look elsewhere for further assistance.

HT4993 Can i get factory unlock my iPhone 4S at sprint carrier locked

I want my iPhone factory unlock at Sprint Carrier locked, to use any gsm carrier sim worldwide.. Is there any way to officialy unlock it

What part of:
"No Sprint model iPhone can be officially unlocked."
Do you not understand?
There is nothing more I can add to this thread. If you want an officially unlocked iPhone, you have the wrong model. Sell it. Don't want to do that? You're on your own
Good luck.

My iphone 5 is carrier locked to verizon

So I bought a iPhone 5 from my friend, and he told me that the verizon iphone 5 is unlocked so I could use it on any network.
However, when i checked with Apple, they told me that the verizon iphone 5 i bought is carrier locked to verizon.
So I called and asked them to unlock it from the network, and I was immediately refused multiple times.
I am really stuck on what I can do at this point... could anyone in the verizon community care to help me out?
It would save me tons of time and work. Thank you in advance.

Have you tried using a SIM from a different carrier? I know that Apple says it is carrier locked, but there are several instances on these forums where people have "claimed" to have been able to use a different carrier with a Verizon iPhone. I assume you have service with a different provider. Just get a SIM card from them and try it in your phone.
This would not be able to work the other way around, though. Verizon iPhones have both CDMA and GSM radios, where GSM carrier iPhones do not have the CDMA radio.
Hopefully this will work for you, however if it does not, you will have to bring it up with your "friend". It was his mistake. You could sell the phone on a site such as Swappa.com.

Get a new non carrier locked iPhone?

Well I canceled my sprint contract and I'm left with a carrier locked iPhone for sprint, well since I bought apple care + I have insurance on phone. My iPhone 4s has battery issues and if I went to apple and they gave me a new iPhone would that new one be carrier free meaning I could take it to AT&T with me? I think that would be the case right?

Well all the iPhones are the same when new when you activate it to a carrier, the carrier then locks it to its company, so if it's unactivated and they give me unactivated new phone then it's not locked to anything, this should work because I had learned that all the iPhone 4s have same internals because apple designed to work both ways.?

About pessimistick lock in Oracle

Hello,
I have some questions about pessimistick lock in Oracle:
I know if i do a SELECT..FOR UPDATE statement, those records are locked, and just me can opperate on them.. but me - WHO? How i'm identified in Oracle? If i do a SELECT..FOR UPDATE select in an A procedure, then i call the update procedure B, how can i know that both calls belongs to the same user? If someone tries to update the same records, how the server knows if that person is allowed to make those updates or not? because everyone uses the same connection string.. isn't it?
Probably it works if i make a SELECT..FOR UPDATE and i make the effective update in that procedure, but this means that the Business Logic is in that procedure..
Please correct me if i'm wrong somewhere and clarify me.
Thanks!

By default the other session has to wait (no error message):
From SQL Reference SELECT section: http://download.oracle.com/docs/cd/B28359_01/server.111/b28286/statements_10002.htm#SQLRF01702
>
NOWAIT | WAIT
The NOWAIT and WAIT clauses let you tell the database how to proceed if the SELECT statement attempts to lock a row that is locked by another user.
Specify NOWAIT to return control to you immediately if a lock exists.
Specify WAIT to instruct the database to wait integer seconds for the row to become available and then return control to you.
If you specify neither WAIT nor NOWAIT, then the database waits until the row is available and then returns the results of the SELECT statement.

Info about network lock

Hi all,
if I buy iPhone 4 as a gift, is it still locked on AT&T or is it never locked? Because the person I'm sending it to doesn't live in the U.S. and the mobile carrier for him is Vodafone. Thanks folks.

It depends on the country in which you buy the iphone.
ALL U.S. iphones are carrier locked to AT&T and cannot be activated with any other carrier in any other country.

HT1937 i have iphone 5 carrier locked to sprint so how can it be factory unlocked ?

i have iphone 5 carrier locked to sprint so how can it be factory unlocked ?
what is a good way to unlock it as i am in UAE now

Don't waste your time, as I've already stated, Sprint WILL NOT autrhorize the unlocking of your sim slot.
You wasted your money. Return the phone for a refund, if you can, otherwise, sell it to someone that can use it on Sprint's network in the US.

Is this producer-consumer scenario safe about dead-lock?

Hi friends!
I'm developing an application with a producer-consumer scenario. It produces a dead-lock 10% of times approx I execute it . I think the real reason of the crashing resides on the concurrency, because executing only the following code it gets the "main" waiting blocked during its execution after looping the do{...}while(true) sometimes. I've developed this code:
public class CubbyHole
    private int nFinishedThreads;
    private int nTotalThreads;
    public CubbyHole(int TotalThreads)
        this.nTotalThreads = nTotalThreads;
        this.nFinishedThreads = 0;
    public synchronized void put()
        this.nFinishedThreads++;
    public synchronized void get()
        while(nFinishedThreads < nTotalThreads)
            try
                wait();
            catch(InterruptedException ie){}
        notifyAll();
//import java.util.Random;
public class Producer implements Runnable
    private CubbyHole container;
    public Producer(CubbyHole container)
        this.container = container;
    public void run()
        System.out.println(Thread.currentThread().getName() + " has begun");
        try{
            Random rand = new Random();
            Thread.sleep(Math.abs(rand.nextInt()*10));
        catch(InterruptedException ie){}
        System.out.println(Thread.currentThread().getName() + " has finished");
        container.put();
public class Consumer implements Runnable
    private CubbyHole container;
    public Consumer(CubbyHole container)
        this.container = container;
    public void run()
        System.out.println(Thread.currentThread().getName() + "is waiting for all threads to be finished");
        container.get();
        System.out.println(Thread.currentThread().getName() + "says all threads have finished");
public class Application
    public static void main(String Args[])
        do{
            int nThreads = 2;
            CubbyHole container = new CubbyHole(nThreads);
            Thread[] ProducersArray = new Thread[nThreads];
            for(int i=0; i<nThreads; i++)
                ProducersArray=
new Thread(
new Producer(container));
ProducersArray[i].start();
Thread finalWait = new Thread( new Consumer(container));
finalWait.start();
try
finalWait.join();
catch(InterruptedException ie){}
System.out.println("Application has finished correctly");
while(true);
Please, execute it and give me your results: is the "main" waiting blocked to you?
Is this producer-consumer code safe about dead-lock?
If the answer is no... Why is it waiting blocked?
Thank you in advance.
P.D. I'm spanish, so my english is horrible! I'm sorry!

Thanks ejp:
Moreover, I suppose nothing happens if I write notifyAll() in both methods, put() and get(). In fact this matters only if the producer overwrites the memory space where data is stored, which is not my case.
Is this so?

My friend bought an iphone 5 with ios6 and he was not told it was carrier locked. what can he do?

My friend bought an iphone 5 with ios 6 installed and he was not told it was carrier locked. what can he do since he doesn't know the carrier?

And there lies his problem.
As I said, call AppleCare and they will let him know which carrier it is locked with. Then he needs to contact that carrier and see what their unlocking process is and if he qualifies. If he doesn't he needs to return the iPhone and get his money back.
