Next week in Berlin, Microsoft is expected to announce at two new Windows Phones, specifically the Lumia 730 and Lumia 830, both mid-range Windows Phones.

This morning, new photos of the Lumia 730 – first revealed by us a few weeks ago – have hit the web ahead of the press event. Even more, the photos confirm what we suspected: there are single SIM with 4G and dual SIM 3G variants.
