Apple's iPhone 12 launch is right around the corner and we're anxiously waiting for. While there have been a plethora of leaks and rumors surrounding the device, the final word rests with the company. According to the latest, it has been discovered that the iPhone 12 models could feature a 'Smart Data Mode' which will seamlessly switch between 4G and 5G connectivity. The process is automatic so the entire process is done under the hood. Let's dive in to see some more details on the subject.

Apple will bring 5G connectivity to the entire lineup of the iPhone 12 models.
