Does anyone have a way of doing this? I called Tech and their emulators show it being available in the wireless networks inside settings < more settings < mobile networks, but none of the 4 S3's I have access to have a "wireless networks" option. The VZW tech was at a loss, and said he put a feedback in about it for the emulators to be updated. I would really like to have a toggle for this since I don't live in a 4G area and I know this draining the battery looking for a 4g signal. TIA.
