Does data downloaded over wifi count against my data plan on the Iphone 4?

Hey you had emailed me looking for help and to answer your question: No it does not count against your data plan. When using WiFi the data that is being streamed is done over the WiFi connection's service provider. Only data streamed over 3G or 4G connection will count against it. Also, sometimes they will count downloads of apps or other services towards the data plan so be careful for that.
