The Lumia 620 is a low-end version of Nokia's flagship Lumia 920. It runs the new Windows Phone 8 operating system. It comes in a bunch of cool colors.
If you read Nokia's review, that's about all the insight you'll get. Most of the piece is a walkthrough of how to set up the device –– "the first thing you'll want to do is personalise the Start screen..." –– and the rest is just a list of the phone's features.
But hey, that's probably the kind of review Nokia fans want to read anyway, right?
