iPhone 4S Launches in 22 New Countries with 1-2 Week Estimates for Online Orders
iPhone 4S order page for Apple's Swedish online store
While Apple does not offer online sales in all of the new launch countries and customers looking to purchase subsidized models on contract will not be able to purchase online, Apple is currently quoting shipping estimates of 1-2 weeks for unlocked devices in nearly all of the new markets with online stores. The lone exception is Singapore, where all iPhone 4S models are listed as currently unavailable. Demand for the iPhone 4S has been high in that country, with reports indicating that carrier partner SingTel sold out of appointment slots to purchase the device within 90 minutes of opening registration earlier this week.
