Those who have bought an iPhone in the United States are in a hurry

1. Without signing a contract, the iPhone 3G 8G is $499. $599 for iPhone3GS 16G, $699 for iPhone3GS 32G. But even if you don't sign a contract, there is still a SIM card lock, that is, you can only use the SIM card of AT&T in the United States.

2. You can buy it at an Apple retail store or AT&T.

3. AT&T number selection and payment.

4. You can't use a SIM card other than AT&T without unlocking your iPhone. And now the new iPhone is a system, and it is impossible to unlock it under the current system.

5. There is nothing available for cards now, and the era of cards is over.

6. The last way is to spend money to disassemble the machine and disassemble the chip, which is not recommended. It is said that the soft unlock will be released after the release of the iPhone 4 generation and the system on June 7. The soft solution of the system is also estimated to be very fast.

Don't you read the words, it said above, there is a lock that is not unlocked or hard to unlock can not use other companies' SIM cards. I advise you to buy unlocked, such as Hong Kong version, New Zealand, Russia, Italy, etc.

Of course, I will wait for the iPhone4 to come out before buying, and then the iPhone3GS will be reduced in price according to the previous pricing strategy.

So much, I think it's necessary for you to add 40 points o( o

How can it be so complicated, I'm from Shenzhen, just take it and change it.

Hello, First of all, I would like to explain that I am currently a student in the United States, and I have been here for a year, I dare not say that I am an expert, but I can also guarantee that what I am saying is the actual situation, and I will not be fooled by you.

1.There are basically four major operators in the United States, AT&T, Sprint, T-Mobile, and Verizon (just think of the domestic mobile Unicom Telecom).

2.There are two ways to buy an iPhone in the United States, directly at an Apple store or online, and the other is to sign a contract.

3.First of all, let's buy it directly, which is usually called unlocked, unlocked iPhone, such a mobile phone can be used directly when you bring it back to China, but **It's a little more expensive, and the cheapest 16G is $649 for 4S now.

4.Speaking of contracted machines, iPhone has cooperated with three of the four major operators, that is, except for T-Mobile, the other three can sign contracts (generally two years, it seems, I'm not sure about this). When you sign up for a carrier, the phone** drops to $199, but you have to use that carrier's card to use the phone, and you have to pay a certain amount of money every month.

The requirements of different carriers seem to be different) In fact, it is basically equivalent to this operator using a cheap iPhone and trapping you, the user, in their company for two years.

That's pretty much it, I hope it helps.

You didn't say how many generations you bought...

1. There are now 4 generations of iPhone. The higher the algebra, the better and the more expensive.

At present, the 1st generation iPhone and the 2nd generation iPhone 3G have been discontinued and withdrawn from the market, the 3rd generation iPhone 3GS will be discontinued in the 16G 32G version, and only the cheap 8G new version will continue to be produced with new phones.

Then there's the latest iPhone 4 generation, which will be released in the US, France, Germany, the UK and Japan on June 24.

2. You need a credit card in the United States to sign a contract to buy, and the first payment is not a few dollars cheaper than not signing a contract, Americans are not stupid, don't be whimsical and open friends.

There are bare metal purchases that do not have a contract, which are more expensive, depending on the generations, and the GB number is 499 599 699 US dollars.

3. Attention! The American version of the iPhone has a SIM card lock even if it is bare, and you can only use the SIM card of the American AT&T company. You need to unlock it softly before you can use the domestic SIM card like the lock-in port version.

At present, the new machine is a system, and it cannot be unlocked by soft solution!

**Almost, it's not worth it compared to the lock-free port version, it will be very troublesome to use after having a lock, and it will become bricked if you are not careful.

In short, it is recommended to buy the Hong Kong version without locking,**Almost, no need to unlock, and it will not become bricked, and the warranty is relatively convenient.

You're so funny, when you sign a contract, you're going to deposit your money there, you're a fool to be a human being.

Signed 199 299

Non-contracted amount 599 699

It didn't work, I bought it in Seattle and my friend bought it before, and he went to see it several times before, and the price difference between signing and not signing was very far away, and he thought about it, and finally gave in, haha. But I have a classmate who bought it on the Internet, and then went to the United States to buy a ** card at a telecommunications company, in fact, it is not much cheaper to go to the United States, and the quality is the same, buy the Hong Kong version and crack it, why bother to buy it here

No matter how much.

If you buy an American machine, even if it is a termination machine or a bare metal, it will not be able to be used when you return to China.

It's because the iPhone in the United States is locked, and you can only use the AT$T SIM card. Domestic cards cannot be used. Although the latest one has a perfect jailbreak, it can't be unlocked yet.

And today out of the iphone 4,3GS Hong Kong version** has also dropped a lot.,It's recommended to buy a Hong Kong version to use.。。 You can also jailbreak perfectly without unlocking.

Good luck.
