Register an account on iTunes Store with and without a credit card [UPDATE 2012]
In the STORE section, select iTunes Store ( located on the right side of iTunes )
We are trying to download any free application in the Free Apps section by clicking the Free button, (Important !!! The application should be FREE, from the Free Apps section)
In the pop-up window, click the button Create a new account.
To continue the process of creating an account, click Continue.
We read the legal information, put a "tick" and click Continue
Fill out the form (I recommend using the box in the .com zone) and click Continue (Important !!! The password must contain at least eight characters, including numbers and letters of upper and lower case. You can not use spaces and the same character three times in a row)
In the Payment Method, select None . Fill out the form and click Continue (Important !!! The address must be real. Do not want to specify your own - specify any other, even if found in Google)
All is ready!!!
We are waiting for the letter in the specified box.
After confirmation, you can enter the iTunes Store using your new Apple ID and password you created.
Have a nice work!!!
