Hi Gang, I just got a LG 540R from Rogers without a data plan and then realized i needed a data plan so i got set up with 100MB a month. My question is how much data do apps. use? Is it by the hour when your using the app is it when you download the app? Am i in trouble with only 100MB a month? This is my first smartphone and have very limited computer skills. Any help would be very much appreciated.
