I want to change the name which is displayed below the app icon on the iPhone screen. I use Xcode 4 and I have one target with keys:
You want to change the Bundle Display Name in your project.plist.
Bundle display name : ${PRODUCT_NAME}
should be changed to
Bundle display name : MySuperApp
This changes the label of the icon in iOS without actually changing the app identifiers. If you just change the bundle display name, you won't need to set up a new app id and provisioning profiles.
