Let me preface this by saying I never thought I would be so confused by cellphone plans Long story short, we have two lines on 1 account (both iPhone 3G)...the primary line is elligible for the 3GS upgrade, and the other is not despite both 3G phones being bought at the same time last summer. Our total monthly bill is about $200. It seems that one of the phones picks up the primary chunk of the bill, and the other is discounted due to a family plan. Either way, the total bill is about 2 x $99...just distributed differently. Is there any wiggle room with AT&T for a situation like this? I understand the deal with subsidies, but AT&T has more than made up for it with the fees on the primary line. I'm not interested in upgrading/resigning unless I can get both phones upgraded simultaneously. I feel like alot of this upgrade eligibility nonsense has alot of grey areas Think I can throw my weight around in the store about this issue or is it pretty much a "sorry I only go by what the computer says" kind of issue?
