So this has very little to do with the thread but I'm not a fan of making threads in the iPhone forum about AT&T and I'm sure we can all enjoy a little "Verizon Math" story AT&T style.
I have the $39.99 rate plan and while looking to see if my "opt out" was gone as well I remembered that when the iPhone 3GS came out my rate was reduced to $33.99, I also realized that I haven't seen this on my bill for the past few months, yet it is still showing up online. I called AT&T to ask them about this and they told me that the $33.99 rate reflects my company discount which is $10.50. So I asked why it isn't 29.49 seeing as that would accurately reflect my $10.50 discount to which I was told "Because that would be too much of a discount." I asked the rep if he was telling me that $39.99 with my $10.50 corporate discount was accurately reflected as $33.99 and he replied "Yes, it is". I asked him "So are you telling me that $33.99 with a $10.50 discount equals $33.99?" to which he replied "Yes, that is your discount.".
I honestly didn't know what else to say, so I just said thanks and hung up.
I actually think that's worse than the Verizon Math incident.
Sounds like you get the same company discount that I get - 15%. The discount is actually 15% off the voice plan ($6.00) and 15% off the iphone data plan ($4.50) - that's where they get the $10.50 figure.
