I want to restore my iPhone 6 because I can't temper my restrictions passcode. Will restoring my iPhone also take away the money I have in my iTunes gift card? And will my phone number be deleted too?
The money in your iTunes account will remain as it is linked to your iTunes account (the Apple ID) rather than the specific device. Your phone number is obtained through the SIM card in the device, so this is not affected by restoring either.
