Fun, Tours and a $3,000 Bill for Hardly Using an iPhone - New York Times
SAN FRANCISCO, Sept. 9 — When Neil Dingman recently went on a European vacation, he took his iPhone with him with no intention of using it much. In fact, for the 14 days he was there, he used it only a handful of times and had expected to see just a small increase in his next bill for roaming charges.
Instead, he was charged $852.31.
As it turned out, the cellphone carried by Mr. Dingman, a mortgage consultant in Minneapolis, made calls on a European data network several times each hour to check for e-mail messages.
Snicker.
