I put my T-Mobile SIM card on an iPhone 2G. I used to have a Samsung Behold. The iPhone is unlocked so it works fine. I was wondering if I'd get charged for internet if I don't use it. The iPhone still picks up EDGE (top right corner has an E). When i go to a site it brings me to a site that says ' you will be charged $1.99/MB for data access'. If i don't use Safari, or the App store, or anything else that uses Web on the iPhone, will i still get charged?
