Gadget lovers worldwide are already camped out ahead of Friday’s global rollout of the new model of Apple’s iPhone, which is also the first iPhone to go on sale in many countries. Carrier SoftBank, which beat market leader NTT DoCoMo for the right to sell the iPhone in Japan, is planning a countdown ceremony at its flagship downtown Tokyo store. By late Thursday, a line of nearly 800 iPhone fans snaked around the block, with some sleeping on the streets to ensure they would be among the first customers.
