Merry Christmas to you all! I just got my Dad an iPod Touch for Christmas, and he loves it. However, my mother intervined and wondered if my Dad should exchange it for an iPhone since he will be getting a new smart phone for his new business. I already have an iPhone 1st Gen. with EDGE service. I pay about $70 a month. Now, if my Dad decides he would like the iPhone 3G instead of the iPod Touch, how much will it minimally cost a month with a plan with 1 iPhone EDGE phone and 1 iPhone 3G? Thank you! I tried reading AT&T's information, but I couldn't understand it for some reason!
