Hello all, So I got the black 4S on Oct. 14, to upgrade my 3GS and renewing a 2-year individual contract with AT&T. My wife's white 4S is still not available at Best Buy. We were planning on going on a family plan with both our 4S, but because her 4S wasn't available, it was better to keep my individual plan. As of today, Best Buy still does not have her pre-order. Now am thinking of just ordering from the online Apple Store. However, if I choose the option to create a new family plan, it tells me to go to an Apple Retail Store. With stocks so low in the retail stores, that is not a good option. Can I choose the other option that says add to an existing plan? Then when I get the iPhone, we'll go to an AT&T store to change my individual plan to a family plan with both our 4S? Thanks in advance.
