Basically - iPhone demand completely overwhelmed ATT and not only were they not prepared it looks like they've been slow to stay on top of things as more and more users sign on. Apple really needs to start selling the handset on all carriers here in the U.S.
I agree with this....working in the call center I hav eseen it over the years.
When the first iPhone came out things were pretty normal....as the 3G came out, more calls about service and quality issues, and they have increased as the 3Gs sold more and more
The iPhone was an unexpected strain I think. Let it go to Verizon or TMobile and I suspect the same problems will occur over time.
