From AP:
The head of mobile phone operator O2 has apologized to customers in the British capital who were unable to make calls after the group’s network was swamped by people using smart phones such as Apple Inc.‘s iPhone.
What does AT&T do when smart phones clog the network? They tell customers to not use it so much. Ma Bell has had the iPhone in New York for about 30 months and I haven’t seen a single apology.
