“Wi-Fi Calling and tethering/Wi-Fi sharing are not currently supported on the T-Mobile G2. T-Mobile knows these features are important to consumers and we’re working to deliver them to G2 users in the future. We have nothing further to announce at this time.”
However, only few people got this update. We are not talking about 15K people per day.. nope. just a few..
Seams we have to wait and wait.
