Sprint forces you to have a data plan AND pay their "premium" data charge. I do not use the data service on my iPhone 4S because, in a word, it stinks. I opt for using WiFi. However, since I am not paying the bill and had no choice in the matter, I just ignore it and leave the data turned off on the phone. My battery lasts a heck of a lot longer than it did when I used to leave it on. My billing period ends on the 10th and my usage so far this cycle is 0.0MB. -- I support the right to keep and arm bears.
