The only way you can edit a App Name (assuming the app has been approved) is by creating a new version, at that point you can modify it.

You can change the name of your existing app only when submitting an update of your app binary. If you submit an app name which is already in use within the same geography in which your app is sold, you will be prompted to enter another name.

If the name change is significant but the functionality is not changing significantly, then the App Store won’t have an issue. But if the app has been released, and the name change is significant and the functionality is significantly different, then the App Store will tell you to submit under a new bundle ID.

When you change your Apple ID to an @icloud.com, @me.com, or @mac.com account, you can’t change it back to a third-party email account. Your former Apple ID that ends with a third-party email becomes an additional email address for your Apple ID account.

You can change your Apple ID to any other email address* you control, as long as it’s not already in use as an Apple ID. If your email address ends with @icloud.com, @me.com, or @mac.com, you can’t change your Apple ID to a third-party email address.
