T-Mobile G2 WiFi calling and tethering update begins rolling out today?

Get ready G2 owners because it looks like an OTA update will begin distribution on November 3rd (yes, that's today) to flip the switch on WiFi tethering and T-Mobile's WiFi Calling for Android feature. The anticipated update lets G2 owners make voices calls and send SMS messages from WiFi networks without a femtocell thus conserving their monthly contractual network allotments -- something that could prove very beneficial at home. It also includes WiFi hotspot tethering (a native part of the Android 2.2 Froyo OS) although T-Mobile won't have data plans ready at the same time. In other words, enjoy your free WiFi tethering while it lasts.
