Hello all. So i am fastly becoming an app junkie.. n there r so many great free apps out there. I noticed that most of these free apps come with ads built in somewhere in the app. My question is if these ads r using up my 3g data usage while they r in the background n i'm not using the app. If this topic has been already posted i apologize but there r so many postings, i couln't go thru it all, looking 4 the answer.. thx
