Was Nokia’s recent cavalcade of new Lumias not enough for you? Don’t worry, there’s yet another model on the way — Chinese regulator TENAA has approved the Lumia 525, a previously rumored refresh of the entry-level 520. As the name suggests, the Windows Phone likely won’t be a radical break from the past. Photos that briefly appeared at the Chinese agency (and were first caught by LiveSide.net) show a device that closely resembles the 520, including the flash-free rear camera. We don’t know much about what’s inside beyond 3G and WiFi, although an earlier rumor at BlogJack has the 525 doubling the onboard RAM to 1GB and putting a greater focus on music. The clearance doesn’t necessarily confirm an imminent launch. However, there have been murmurs at Nokiapoweruser of a launch by early December; those who want yet another frugal Lumia may not have long to wait.
