Details about a pending update to Windows Phone 8 (MSFT, NOK), known as GDR2, have been released. The update is a relatively minor one, delivering features such as messaging improvements, FM radio support for the Music+Videos app, and improvements to the Skype, IE, and Xbox Music apps. WP's "Blue" update, expected in early '14, is set to be much bigger. The Verge reports Blue will deliver a better notification center (addressing a common complaint) and improved multitasking. The GDR3 update, due earlier, adds support for 5"-6" displays, 1080p, and quad-core CPUs. As with Windows, Microsoft is reportedly moving to a faster update cycle for WP.
