Data plan and WiFi on iPhone 4? Are they interchangeable?

No, if you are connected to WiFi and you see the wireless image in the top left corner of the iPhone then you are connected to the internet through the wireless connection and not using your data plan.

No..when you are on WiFi, you are not using up your data.... When I am home, I use my wireless router and no 3G data being wasted.! (Too bad all my neighbors have locked wireless.) :).

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
