I recently bought a GS2 and was wondering how do you completely kill the connection to the data network? I am on WiFi 95% of the time and have found that even when I am on it, the 4G activates and does whatever mystery downloading. For example yesterday I was home all day and had 16m of data move on cell data all the while I was on WiFi at home. I've gone to Wireless & network > Mobile networks and disabled Use packet data but it keeps turning on by itself. I have a couple of apps, Onava and even the GO Switch widget to disable it but it keeps turning on. There must be something running that is activating it? Any ideas?? I must say it was much easier with my POS iPhone to kill the mobile network and as much as I loathe that phone it was never as shady as some of the background stuff that happens on this handset. I have a task manager widget running and one minute it is cleared and the next it is packed with stuff running. Frustrating as heck..
