Was really waiting for all carriers to come up with their prices before posting this, but I guess I can’t be bothered to wait for Starhub.
M1 was the earliest with their prices, and these were released since last Friday.
M1’s launch is a first come first served event at 12am at the usual Paragon M1 shop, with no web preorders allowed until the 28th itself, unlike Starhub and Singtel.
Other M1 shops will start selling the iPhone 4S at 7am on 28th October 2011.
