Firmware Update will activate FM Radio & Double Tap to Unlock on Nokia Lumia 920 & Lumia 820

Sources familiar with Nokia have disclosed that Lumia 920 and Lumia 820 will be receiving a software update that will not only activate FM Radio hardware inside those devices, as well as enable double tap on the screen to unlock the device in similar fashion as of Nokia N9 (MeeGo Harmattan). Other firmware specific improvements from Nokia will include a flip to silence option, and Lumia color profile settings for the device screen.

This software update will be minor in nature and will be made available for Windows Phone 8 devices in the months to follow.
