The first retail-store buyers of an iPhone 5 on Earth were a pair of siblings and a member of the staff of a mobile phone enthusiast site in Sydney, Australia, which by virtue of its proximity to the International Date Line became the first of the nine countries allowed to sell the new iPhone on Friday morning, local time. Some people, including paid line-standers and those advertising for various companies or causes, stood in line as long as 68 hours when queues started forming on Tuesday for the hit smartphone.
