Yes, also just to add that the 4G systems , while has some elements of cellular technology in nature, is more for Data purposes and not voice network. I spoke to our rep and he said that they're looking into LTE as a solution to offer broadband access to phone's rather than really do away with traditional cellular technologies. Now it's up to the discretion of the carrier whether or not they want to go on a system to route voice traffic on this data network, but we won't know till the infrastructure is in place, and the handsets out!
