Hi. So i think i'm going to leave Alltel in search of the mighty Iphone. I would like to know the main differences between the 3G and 3Gs. My main concern is what my bill will look like every month. I know that i should go to AT&T and speak to them, but maybe you can save me a trip or give me advice before i head there later this week to see what's up. Are you truly happy with your Iphone is mainly my question, and is it true that it will cost $100 a month!?
