Myself and my family are on a T-Mobile family plan. We're looking to switch to AT&T because T-Mo service is absolutely terrible here. So I was planning on just all of us going to the AT&T store which is down the road from me. My family just want regular phones with voice plans, whereas I want an iPhone 3G. I thought we all could just go there and get our phones activated right there and take them home, with me on the family plan but with my own data plan (is this possible by the way?) I figured this would just be fine but I've been reading some threads that is actually makes a difference where you get your iPhone. Is this true? Does someone have a better idea of how I can go about steering my family in the right direction in order to switch over as well as giving me the iPhone? EDIT: Should I buy the iPhone elsewhere, like at Best Buy un-activated and just bring it to the AT&T store when my family wants to switch over and get their phones activated so they can activate my iPhone?
