Owners of the HTC One M8 for Windows on Verizon Wireless should be on the lookout for a software update today. We have received a number of tips alerting us to an over-the-air update for the smartphone, and Verizon's website has confirmed they launched an update. It will bring the OS version of the phone up to General Distribution Release 2 (GDR2), otherwise known as Windows Phone 8.1 Update 2.
