Successor to Nokia's Lumia 610 in the works, with Windows Phone 7.8?
Codenamed “Glory,” this device is said to have a 4-inch display, an 800 MHz processor, 256MB of RAM and Windows Phone 7.8. No release timeframe was reported, but we can safely expect that it will not be part of the big announcement anticipated on September 5th.
If this comes to fruition, it will keep the Windows Phone 7.x landscape relevant and accessible with some fresh equipment for those that could not (or would not) pick up a higher-end Windows Phone device.
