I got the samsung infuse 4g a couple of days ago and am on a 200mb data plan. Now, I've read what others classify as a light user, and from that I'm going to say that I am a VERY light user. I left the wifi off on my phone today and realized that I had used 20mb of my 200mb. Now my Wifi is enabled, and set to never turn off while the phone is asleep. In addition to that, I've also disabled all background syncing and data collection. Nothing updates unless I open the program. Is there anything else that could possibly eat up my data plan? If i'm in an area with no wifi, will some processes still use the data plan, even though I've disabled all background data and syncing? Thanks for the help.
