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.
