One of my net friend in HK told me that there is an ads about Galaxy S and sandisk are having a promotion for 32 GB micro SD card. She told me that Hong Kong will have the first lot of the card. But the ads just in Chinese.

I think it is better to find the card from HK like dealsextreme and dragonext.com.
