It’s hardly a secret that Apple will unveil an upgraded iPhone at its Cupertino event on Tuesday. But that one phone could just scratch the surface of what shows up. Here’s what you should — and shouldn’t — expect from Apple’s announcements tomorrow at 1PM ET / 10AM PT. Apple’s next flagship iPhone is expected to physically resemble the iPhone 5, while including a couple of new features. The biggest of those could be a fingerprint scanner that’s built directly into the home button, which could be used for securely unlocking the device. Rumors suggest that it’ll be covered with sapphire crystal for durability, and have a silver ring around it, which would for the first time change how the home button looks. Camera upgrades are expected to be minor, if much happens at all.
