Question for anyone....Has anyone been out of the country with this phone yet. I am flying to Brazil tomorrow and was hoping to use the video chat with Fring or Qik to show some live videos back home in TX. I was curious what kind of settings would have to be changed to make this work. I know there is no Sprint network down there, nor any 3G or 4G. But I assume as long as I was in a wifi spot (hotel, cafe, bar, etc...) that the phone should still be able to connect and use those video chat apps? Any help or experience with this? I am hoping there is some type of setting I haven't found yet that basically turns off the cellular network functions of this phone, but keeps the wifi option available.
