You can't get an international warranty for your mobile phone.
Think about that for a minute. The electronic gadget that you are certain to take with you when you go abroad doesn't have a worldwide guarantee. And that cool new cellphone you buy when you're on vacation won't be covered if it breaks as soon as you get home. That's the situation in much of the world for phones from Nokia, Motorola, Sony-Ericsson, and other vendors.
