How to create an apple ID on iphone 4? And how do you delete an apple ID?

I'm not sure how you delete one, but go into itunes and into the itunes store. There should be an option near the top to sign in and then a link to make an ID. It says something like "no ID?". Just sign up that way, you'll have to have a email you haven't used for a previous ID.

Apple ID is permanent.
If you have alot of email acc, you can create alot Apple acc. But its useless to create alot
