Shalamazoo, I don't think there is an English version of the site but it does list current prices in HK.
The columns refer to different shops, from left to right they are: Fortress, Broadway, Gome, Wilson, Wing Shing, Citicall, PCCW, CSL1010, Three, Peoples, SmarTone, and Parallel imports (Grey imports).
Actually that site doesn't mention a lot of phones that are available both Grey and on the main market, the Nokia N81 for example - this has been available for a while. So I wouldn't take the list a a truly representative example of whats available in HK.
Usually if a phone has been released elsewhere in the world for at least 2 weeks you will probably find it in Mongkok! I haven't been down there for a couple of weeks and wasn't looking for this model but it would be the first place I would go - if it's not there then it's not anywhere.
