So I've been using my phone for a week or two now, and recently installed a data manager app to keep an eye on my data usage. Turns out my OS Service uses a lot of data each day. I've looked at similar threads here and tried out solutions, but it's still using around 80Mb a day. I've turned off: "Back up my data" I don't have a Live Wallpaper. The only accounts that I sync are Hotmail and Gmail, and they both have separate icons in the data manager. Anyone else have this problem? If this continues I'll be using 2Gb a month on just OS Service without even using the phone.
