I know I'll eventually need to call at&t regarding this question but, until they get their story straight (hopefully before the 11th), I'm not going to waste my time on the phone with them.
I'm currently on a 3 year old family plan with my wife and neither of us have iPhones. We pay $60 for the first line and $10 for the second for a total of $70 before taxes and fees. The company I work for gives me 23% off my monthly bill but that only applies to the $60 line (so little less than $14 off). So it roughly comes to: $60 (line 1) + $10 (line 2) - $14 (discount) + $10 (tax) = $66
I guess in the past, even if you had a family plan there was always one line that costs $60 or more and then the second line was the $10 one. The first two lines were treated separately and my discount only applied to the primary line. However, it seems that now a "family plan" by default includes two lines grouped under one price for both of those lines. If I sign up for the $130 two-iPhone family plan, it will incur one flat price for two lines which is all the lines we need. If that's the case, and it turns out that corporate discounts do apply, then the only number to apply my 23% off discount to is the $130 amount. That's a savings of almost $30! It's like getting one of the iPhone data packages or unlimited text messaging for my wife and I for free.
Does that make sense and is that how you think the discount on a current iPhone family plan would work? With my plan I have now it seems that the difference between the primary line and the secondary line is the unequal price as well as the designation on my account. But with the new iPhone family plan, it seems that the difference between the primary line and the secondary line is only the designation in at&t's system.
Help me out here, as I've been going back and forth since WWDC
