I've been looking for a location profile app that will let me run wifi at work or home with 4G disabled, and then disable wifi and enable 4G when I leave. Llama is great, except it doesn't seem to be able to toggle 4G in ICS, and from what I've read the same is true for Tasker. I can manually toggle 4G on and off with Power Toggles, but are there any location profile apps that will let me automate this? Smart Actions doesn't seem to help, as it's great at enabling services when I arrive at a location, but it doesn't turn them off when I leave. Thanks in advance for any suggestions.
