You need to install the new profile again on your computer and device.
Go to your iPhone 'Settings' then 'General' and scroll to the bottom to 'Profiles'. Then delete the old one.
Also, when you double-click the new profile to add to your xCode, you might also see the old one listed there. It's probably a good idea to select and delete this one too in xCode.
