My Status: I've had an ATT cell phone, on an ATT family plan for yrs. I'd prefer to stay w/ ATT. I'm eligible for a phone upgrade soon. What I want: I want to get an iphone and use it for the phone and sync it to my iMac to use as an ipod, contacts, calendar, wi-fi, ect. What I don't want: I do NOT want (1) the edge or 3g network, (2) the monthly data plan, or (3) any data charges. My Questions: (1) Can I avoid the monthly data plan and all data charges ? And does the answer change depending upon whether I buy (1) a used 1st generation iphone, (2) a used 3g iphone, or (3) a new 3g iphone? (2) After I buy the iphone, what do I need to do to get the phone service activated and avoid the monthly data plan charges and data use charges? Again does the answer change depending on whether I buy (1) a used 1st generation iphone, (2) a used 3g iphone, or (3) a new 3g iphone? Thank you very much for any helpful advice.
