Apple, the well known maker of the wildly popular iPad and iPod, is finally selling an official unlocked version of it’s latest smartphone, iPhone 4S, in the USA. It’s now possible for business and pleasure tourists, who have long desired to travel to India from USA with their iPhone, to have one model work at home and abroad.
