(as if we needed another) reason never, ever to buy version one of any machine, no matter how revered and prominent the company that sells it.
A family took their iPhones on vacation outside the US. When they returned home it was to bills of $5,000 on those phones.
It turns out that iPhones check e-mail at regular intervals without prompting. Those phones were eating hundreds of dollars in net time every day without owner intervention.
Oh sure, all charges are "legitimate" according to the phone company. Just like all charges on a stolen phone are "legitimate".
Leaving US cellphones home and buying a disposable at one's destination seems to be the only way to go. If you lose it, only a bunch of prepaid minutes are available to the finders -- and your disposable will never make transatlantic calls to check e-mail, of all the stupid tricks.
