I just got an iphone 5 from verizon with the cheapest data plan. I know data means using the internet (email, facebook, youtube, netflix). I was wondering if having multiple browsers open wastes data, also if it is possible to use data while the phone is off. I know this might sound stupid but does "data" mean taking a picture, listening to music, playing games (downloaded apps), siri?
Does syncing songs from itunes library (on laptop) to my phone take up data? I'm really confused, please help:) Thanks
