Before transferring data from your old phone to your new iPhone 15, it's essential to ensure your new device is updated to iOS 17.0.2
This update, released recently, addresses an issue that could potentially hinder the direct transfer of data from another iPhone during the initial setup. Please note that iOS 17.0.2 is exclusively available for the newly launched iPhone 15 models. If you encounter prompts to update when starting the transfer process, it's advisable to proceed with the update to ensure a seamless transition.
In related news, the iPhone 15 and iPhone 15 Pro were officially released on Friday, introducing several enhancements, including USB-C ports, refreshed external designs (including titanium finishes for the Pro models), and improved camera capabilities.
