The 710 has appeared over at Nokia USA's official website as "coming soon." There are no specific details on when to expect the handset Stateside, though. However, Nokia did say that it would bring Windows Phone devices to the US in early 2012, so that's when the 710 will likely be available.
The Nokia Lumia 710 features a 3.7 inch WVGA ClearBlack display, 1.4GHz processor, Wi-Fi, GPS, Nokia Drive, 5MP camera with LED flash, 720p video recording, and 8GB of internal memory.
In Europe, the handset will cost €270 before taxes and subsidies. That's about $378 - which means the smartphone could be offered by a US carrier for under $100 on contract. Of course, we don't know what America carrier is interested to offer the Lumia 710 yet. Maybe Verizon, since it had staff present at Nokia World. We'll see.
