I am pretty sure Apple can always lead the way in electronic field as the marketing strategy is awesome and extremely fast. Since iPhone 5 officially launched yesterday, Apple already open for iPhone 5 pre-order in many countries around the world. Singapore is one of the first country to receive iPhone pre-order from official Apple store or you might just register interest for iPhone 5 at Singtel, Starhub and M1. For those who pre-order from telco, the package and plan will only announce on 21 September 2012 while for pre-order from Apple store, shipping will starts within two weeks from now.
