How do you change your iPhone app store address?

First of all, you have to realize that your iphone app store passWord is the same as your iTunes store passWord. In order to change your app store passWord, you have to log into iTunes, and an effective way I've found is to activate your account by actually downloading something. The easist thing is for you to do this in iTunes on your computer while the iphone is hooked up to your computer.

Good luck. Hope this makes sense.
