Apple quickly released a carrier update for Verizon which seemed to fix the issue, however AT&T customers have been left in the dark.
AT&T points the finger at Apple, instructing customers to turn off cellular data for all system services, and often credits the customer. Apple on the other hand has yet to acknowledge the issue even exists.
When contacted by Forbes' Steven Rosenbaum, an Apple senior advisor had this to say:
"I have reviewed your message regarding the data usage. What I have researched about this issue is the data usage from your iPhone can be high and I understand that a plan with data can be costly. But my input about that is if you can be ok or are able to better manage the data usage the iPhone has, that is great. However, if you feel it is best to change in order to keep a handle on the data your phone uses, that’s ok. I am glad to help you with this issue in any way I can.
Sincerely, ~ Rob Armstrong
Apple iOS Senior Advisor
AT&T's official response to the problem is even less helpful:
We appreciate your feedback and have taken it to heart. While your situation appears to be an anomaly we always want our customers to have the best experience possible, and we’re working every day to make our customer experience even better.
Mark Siegel AT&T spokesman
It appears as though the companies have been blaming each other for the problem while customers are stuck footing the bill. According to Forbes, the situation has reached the point where customers are contacting the FCC who is investing the allegations.
However, there does appear to be a ray of hope, Forbes now says there are rumblings of a high level meeting between the companies to address the issue.
