Apple has launched iPhone 4S in 22 additional countries, as it announced it would by the end of October, making the launch the company's fastest international rollout of an iPhone with the 4S model now available in 29 nations.

Apple initially launched iPhone 4S in the US, Australia, Canada, France, Germany, Japan the UK, and has now added Austria, Belgium, Czech Republic, Denmark, Estonia, Finland, Hungary, Ireland, Italy, Latvia, Liechtenstein, Lithuania, Luxembourg, Mexico, Netherlands, Norway, Singapore, Slovakia, Slovenia, Spain, Sweden and Switzerland.

The iPhone 4S is already off to a record-breaking start in its first seven countries, where sales topped four million in its first three days of availability. That handily outpaced the 1.7 million units of the iPhone 4 Apple sold in June of 2010.

Along with its carrier partners, Apple began taking online preorders for the new phone one week early in many of the additional 22 countries last week, citing estimated shipping times of one to two weeks.



In most countries, online orders are still providing a one to two week shipping estimate (as appears above, for online orders in Switzerland). Apple is only selling unlocked phones online, with carriers handling purchases tied to contracts.

Both Apple and its SingTel carrier partner have already sold out of the new model in Singapore however, with Apple listing all three capacity models in either color as being "currently unavailable," with no estimate on availability.



A report by AsiaOne notes that SinTel was overwhelmed with demand for the new phone, with preorders exhausted within 90 minutes of the carrier opening up orders.
