This year, Nokia made official two Windows Phone 8 devices, namely the flagship Lumia 920 and the mid-ranger Lumia 820, and has already started to bring them to shelves in various markets around the world.
In the United States, for example, while Lumia 920 will be exclusive to AT&T, Lumia 820 will be released at more wireless carriers and in different forms.
Thus, while T-Mobile will get the device as Lumia 810, Verizon Wireless’ customers will be able to purchase it as Lumia 822. Lumia 820 will be launched at AT&T as well, in its original form.
Clearly, there are a series of differences between the three models, and Nokia took its time to present the main features that can be observed from one unit to another.
AT&T’s flavor of the device will arrive on shelves with 8GB of internal memory, 4G LTE, a front camera of 640×480 pixels and a 1,650 mAH battery inside. It will be accompanied by interchangeable shells in five different colors.
T-Mobile’s Lumia 810 will offer support for the wireless carrier’s 4G HSPA+ network, 8GB of memory, 1,800 mAh battery and cyan and black interchangeable shells, as well as with a front camera with support for HD-resolution video chatting.
As for Verizon's Lumia 822, it was designed with support for Verizon’s 4G LTE network, features 16GB of internal memory, an 1,800 mAh battery, HD front camera, and interchangeable shells in grey, black and white.
All three models with pack a 1.5 GHz dual-core Snapdragon S4 processor inside, along with a 4.3” OLED Clear Black Display capable of delivering an 800×480 pixels resolution.
They also sport the same 8-megapixel camera on the back, with support for full HD video recording, as well as MicroSD memory card slots with support for up to 64GB of external storage space.
The outer design of these different flavors of the same device is different as well, with more rounded corners on Verizon’s version, and sharper edges on T-Mobile’s Lumia 810, for example.
