Hello guys, sorry if this issue has been resolved beforehand and/or is an elementary concern but... If I have an existing phoneline with AT&T, could I simply buy an iPhone tomorrow and establish a familytalk plan? One line being my current LG phone and the other my iPhone? The only reason I am asking this question is because my current line is not eligible for an upgrade. I was told today by a rep that the only options for existing customers were either to terminate your current line or pay an extra $200 for an early upgrade fee. Will this be too much for an Apple rep to comprehend or is this a regular occurrence? Thanks in advance!
