4G speeds in my area are so fast that I wasn't really missing wifi, but I flipped it on so I could connect to my access point.
A message came up that said that all voice and text traffic would now take place over my wifi network rather than the cell network. A very cool feature indeed. My question is though.... once I've rooted, if I flash a new rom, would I lose that voip functionality? I'm assuming yes, but I'm just asking to be sure.
