Can I rename an app existing and then submit a new app with the name of the original?

You probably want to do this:

1. Change the display name of your existing app (see the note)
2. Create your second app with the old display name (adding the info.plist)
3. You cannot change the bundle id but there is no need to do so, just update the display name

Updating the Display Name of Your App

Q: How do I change the name displayed underneath my app icon on my device's Home screen?

A: To change the name appearing underneath your app icon, modify the

CFBundleDisplayName

Info.plist

CFBundleDisplayName

1. In Xcode, click the disclosure triangle next to your app folder in the project navigator to reveal its content as shown in Figure 1.
2. Click the disclosure triangle next to the "Supporting Files" subfolder to reveal its content.
3. Select the

   Info.plist

   file to reveal a property list editor of keys and values.
4. By default, Xcode displays a human-readable string of a key rather than its actual name. So, search the property list for "Bundle display name". Skip to step 5 if your property list already shows

   Bundle display name

   . If it doesn't, add it to your list as follows:
   1. Click on any entry in your list, then click the "+" button.
   2. Choose

      Bundle display name

      from the ensuing pop-up menu.
   Note: To display the actual key names, control-click anywhere in the property list editor, then choose Show Raw Keys/Values from the appearing contextual menu.
5. Double-click in the Value column of

   Bundle display name

   .
6. Enter a new value for

   Bundle display name

   as shown in Figure 2.

Basically, yes, but be ready to grab the free'd up name (App A) before someone else does.

And don't delete an app with a name you want - it will go back into the pool for everyone else but you and you can't get it back.

Hi,I have changed "Bundle display name", but the app name on my device still be the project name .How to change it?

Use Xcode's 'Product' menu with the option key pressed, then select 'Clean Build Folder' to force it to forget the cached name - also delete the app off the simulator/device before building again to test - stick w/it until it cooperates.

Will this update the developer name that shows under the name of the app in the app store?
