I just noticed my bill was higher (more than double) than it has been for about 5 years. AT&T charged me three upgrade fees. I only have (and have ever had) one line on my account. The first was charged 9/14 (ordered iPhone online) The second was 9/22 (activated iPhone over the phone) The 9/22 charged was credited back to me the same day. The third was on 10/1 (after I had done an online chat that resulted in AT&T waiving my upgrade fee). My bill is now showing $72.00 in upgrade fees. I am on the phone with CS now. I will update with the result.
