APPLE-ID Question

You can't transfer purchases or merge different IDs together.

Only Apple knows why it doesn't offer that feature - maybe it's part of the conditions set forth by the music labels, by hollywood, who knows - we certainly don't.

You can't permanently delete an account, only "delete" it from a device or computer (this doesn't delete the account, it only removes the connection to the itunes account).

You can't transfer purchases to another iTunes account. Accounts are not deleted (obviously except for the old MobileMe accounts, but my userstanding is that the account IDs are still there, new users can't use any of those.

How do I delete an account from a device?

The account used to purchase apps is entered in iTunes and though it can be the same ID as your iCloud account it doesn't have to be - the two are not connected.

To sign out in iTunes, go to the iTunes Store, click on your name at the left of the black toolbar, and choose 'Sign Out'.

This does not affect your connection to iCloud. If you want to remove your iCloud account from your device, go to System Preferences (or Settings) and click 'Sign Out' (on a Mac) or 'Delete account' (on an iOS device).
