Maybe you’ve experienced this horror yourself. You pull your phone out of your pocket, and the web browser is open. OMG. How long has it been open? It is online? How much are they going to charge me for all that data my pocket presses invoked?
So here’s my big worry about the iPhone: how is the data stuff going to work? It has support for wireless internet access, so if you’re in range of an access point you can use all the web and email features through that network. The question I have is about cellular internet. Will they require people to buy an expensive data plan? If not, and I don’t have a data plan, what happens when my iPhone tries to go online over a cellular network? Will it warn me properly that I’m about to pay a hundred dollars per kilobyte? What about automated functions like email checking?
