Here's the Lumia 820, the Lumia 920's little sister. It's got the same polycarbonate unibody with softer lines. It's also got a 4.3-inch screen, 4G LTE, and built in NFC, Nokia City Lens, and all the other exclusive Nokia apps. Not bad for the second child.
But here's the big part: It's got a pop-off back shell, which means there's room for a microSD card. It also adds Wireless Charging to the 820. Specs aren't confirmed, but it's rumored to have the same 1.5GHz dual core processor and 1GB of RAM, but 8GB of storage, and be on T-Mobile, though Verizon is expected to get this phone when it finally gets around to picking up a Windows Phone from Nokia.
We'll update you with official specs once we have them.
