Unlock your Iphone

Ever wondered why iPhone from the US needs to be unlocked? In the US all iPhones are locked to a carrier,AT&T or Verizon. AT&T allows you to unlock your phone after two years when the contract gets over or if you pay an early termination fee. Otherwise if you want to switch carriers you have to hack into your phone to unlock it. Even this is not simple because on the US,AT&T & T-Mobile use GSM and Verizon uses CDMA. So if your iPhone is only equipped to work on one you cant take it to the other.
The iPhones that are released in India are factory unlocked so users can switch wireless carriers at will without hacking or worrying that future Apple software updates will reduce their iPhones to a brick.



You can unlock your Iphone through the following steps:
First, look up your phone's IMEI number. Go to Settings>General>About and the number will be listed at the bottom. Secondly, contact AT&T by phone, on the web or in person. Third, tell AT&T you want to unlock your iPhone. Provide your IMEI number and wait for the unlocking process. You will also have to give an email address where you will get the unlocking instructions. The email may come in few minutes or in a few days. Fourth, when the mail arrives, you will be instructed to backup and restore your iPhone in iTunes. Open iTunes on a computer that is connected to the internet.
Make sure your iPhone has an active sim card in it. Plug into iTunes and then right click on the phone under the 'Devices' coloumn on the left of the screen and click 'Backup'. Once it is finished, right click on the device and select 'Restore from Backup'. You shoul now get a message in iTunes saying 'Unlock Complete. Congratulations. Your iPhone  has been unlocked'
To set up and sync this iPhone, click continue.
Now you will be able to use your iPhone without a hitch.
