T-Mobile LG Optimus will feature a WiFi calling ability?

TmoNews is reporting that the T-Mobile LG Optimus is going to have a WiFi calling ability, really? As you can see in the image above, have a look on reason #2 and you will see that “Flexibility to make calls during broadband internet connection via WiFi hotspot without using your minutes.” That’s a very good features, and I am sure everyone want this feature in their phone, but not everyone is kind like T-Mo and LG.  T-Mobile LG Optimus is actually the LG Optimus One, which was launched by LG a few days ago, and Verizon is also taking this device. We have seen this device in T-Mobile’s documents too, so I hope we’ll see this device next month.
