Hey there. Next week, I'm ugprading to a white iPhone 3G (16GB), which will be a massive upgrade to both my Motorola RAZR V3t and my first-generation iPod touch. I have a couple of questions: . Does 3G Use add on to the monthly bill? . Does WiFi use add on to the monthly bill? (I wouldn't think so) . Is the performance of the 3G better than that of a first-generation iPod touch? . Any tips/pointers I should know?
