If I buy an iphone 4 from the United States, can I use it back home?

No, you need to crack the network (also called jailbreaking) with reference to the previous iPhone 3GS sold in the UK without locks.

The UK, France and Canada both offer unlocked versions of the iPhone 4 From: Weiphone Apple's iPhone 4 has started accepting pre-orders, and it has been revealed that the iPhone 4 sold in the UK is an unlocked version of the iPhone 4. The iPhone 4 booking page on Apple's official website in the UK says:

The iPhone you buy from the Apple** store will be an iPhone without a SIM card. This way, you can register the carrier network you want to connect to and change carriers at any time. It is reported that Apple will continue to offer an unlocked version of the iPhone 4 in the UK until Apple reaches an agreement with the major major operators in the UK.

The unlocked iPhone 4 sold in the UK** for £499 and £599 respectively.

In addition, according to the latest news reports, unlocked versions of the iPhone 4 are also available in Canada and France. This is the page of Apple's official website in Canada, and there is also a paragraph in it that is similar to that of Apple's official website in the United Kingdom. Canada only starts selling the iPhone 4 next month.

No, the iPhone bought in the United States is locked in the network, unless you don't use iphoe to play **、、、

I'm in the U.S., and a few friends have recently returned home to learn about the situation

1.iPhone4 bare metal in the United States, even if you don't sign a 2-year agreement with the service provider, ** it is about the same as in China, and it is slightly cheaper.

2.If you have a two-year use agreement and pay a monthly fee, the mobile phone **8G should be $199, but the monthly fee is $50+, which is not cost-effective for two years. In one case, you buy it and bring it back to China to unlock it after defaulting, but because the mobile phone agreement is signed with a passport or SSN (similar to an ID card), after the default, it is said that there will be a stain on your credit history when you come to the United States, so it is recommended not to do so.

The United States is a country that attaches great importance to credit, and if it has an impact on going to the United States again in the future, the gains outweigh the losses.

3.Now the customs has implemented a new policy since September this year, and the tax of more than 5,000 yuan has to be paid, and almost all those who have been sampled have to pay taxes.

Hope it helps.

Also, welcome to the United States, go to the ** show, hehe, can you go to see it?

The American iPhone4 is a locked version, and it can't be unlocked when you buy it now.

In terms of cost, 16g without a mobile phone plan is 599 plus tax, depending on which state you go to, the tax ranges from 6% to 10%. If you go to a tax-free state, there is no tax (no tax in the three states of DE, NH, and OR).

Hong Kong buy is unlocked, ** is 4999 Hong Kong dollars, but be careful when you bring it through the customs from Hong Kong, you may be taxed, there is now very strict, but it is more convenient to bring it from the United States to China, and the possibility of paying taxes is very small.

The bare metal is similar to that of Hong Kong. Most of the people who enter the customs now will pay taxes!
