Can anyone tell me how to use the video chat feature Metro claims to be included with the LG Esteem. It has nothing about it in the instruction manual provided with the phone. I think it uses google talk format. But can I chat with my daughter on her Iphone? And is it on 4G or wifi or both? I'm so confused. However I like the Esteem much better than the Indulge even if the video chat claim is only a myth.
