Apple's iPhone 4S is an official sales hit. The company announced today that the latest version of its smartphone has already sold over four million units since it went on sale at brick and mortar retail stores on Friday. Apple claims that those sales number are not only double the amount for the iPhone 4 launch but the biggest sales launch ever for a phone, period. Last week Apple announced it had sold over one million iPhone 4S units in pre-orders on its official web site.
In addition to the massive first weekend sales of the iPhone 4S, Apple said that the launch of the iOS 5 operating system on Wednesday has already resulted in 25 million people now using the new version for the iPhone, iPad and iPod Touch. Finally, the iCloud service has generated over 20 million registered users since launching on Wednesday.
Keep in mind that all of these sales come from just a few countries at the moment: the US, Australia, Canada, France, Germany, Japan and the UK. Apple will likely see yet another sales spike on October 28 when the iPhone 4S goes on sale in a number of other countries. They include Austria, Belgium, Czech Republic, Denmark, Estonia, Finland, Hungary, Ireland, Italy, Latvia, Liechtenstein, Lithuania, Luxembourg, Mexico, Netherlands, Norway, Singapore, Slovakia, Slovenia, Spain, Sweden and Switzerland.
Apple will likely reveal even more information about its iPhone 4S launch on Tuesday when it announces its financial results from its third quarter 2011 time period.
