10 million iPhones shipped by end of this month A group of Apple watchers have been compiling a spreadsheet listing product numbers of iPhones submitted by recent buyers. Presuming them to be sequential, they've come up with an estimate of at least 4,539,700 iPhone 3G handsets purchased. With 2.4 million suckers having shelled out as much as $599 for the firstgeneration model, and factories in China churning out over 800,000 units a week, his hot-tempered holiness Steve Jobs's prediction of 10 million units sold in 2008 could come true well before Thanksgiving.
