I'm thinking the iPhone 5c maybe be for me. I use a smartphone primarily for making calls, responding to emails, and contact management. I don't give a damn about phone cameras, video, games, or any of that. So it would be really great if the iPhone 5c has HD voice on T-Mobile's network, and it also allows wifi calling. If it does, I'm going to buy one. So, anyone know if the 5c will have these options?
