My friend gave me his "extremely" used condition 3G because he will be getting the 3GS on June 19th. But I have a question; I am currently using my iPhone 2G WITHOUT THE DATA. We are not paying the extra $30/month. In other words, AT&T does not know I am using it. I know the whole SIM card deal and can pop mine into the 3G. My question is will they know I am using it and start charging me for the data? Either way, I will not be using the internet. I do not need it. I got it with the intentions of working on it, not really to use much. I am just curious.
