The online sale from Apple Store started from 01:00am 29/4 (Hong Kong time; GMT +8) and all models (black and white; all storage capacities; wifi / 3G) were quickly sold out within 45 minutes. Also, lines started to appear this morning outside many Apple retailers / resellers. I'm not sure they were lining up for the iPad 2 or white iPhone 4. I guess some, if not most of them were scalpers. p.s. Hong Kong has the cheapest price tags in the world due to the absence of sales tax. 1USD ~ 7.8HKD.
