so i have at&t, and had some questions about my cell phone/plan usage. so if i am in a wi-fi area, and connect to the internet, will it charge me on my data plan? i had other q's, but forget them for the moment... oh... is the marketplace considered usage on the data plan? i guess for downloading the apps... that counts towards it as well? if so, my 200 mb will go quickly i think! and how do i view how many texts/mb i have used already of my plan? and does it count against me to receive texts?
