Apple has announced the first 5m sales of its new iPhone 5 over the course of the three days since its launch. That’s 1m more than the iPhone 4S sold in its first weekend in October 2011. Apple says it has sold out of its initial supply of iPhone 5 units, despite plans to put the device on sale in 22 more countries this Friday (28 September). However, analysts reacted with disappointment to the first weekend figure, having anticipated as many as 10m sales in the device’s first three days on sale. It’s a sign of the raised expectations that greet any new Apple device. Separately, Apple also said that more than 100m iOS devices have been updated to the latest iOS 6 software since its release last week.
