I was in HK last week and bought an iPad for a friend. He however decided not to go for the 3G option, which I bought for him since the 16GB only version he wanted was sold out.
So now I am stuck with an iPad 2, 16 GB with 3G, Black.
I bought it for HKD 4.888 so you can buy it from me for that price.
You can pay in HKD or RMB. I can give you the original invoice of the Broadway shop in HK Time Center where I bought it on the 2nd of August last week.
As mentioned it is NEW, still in the original sealed box, with the original invoice. So you can save yourself a trip to HK. I thought you cannot even get a 3G version in China officially. It means you can put in a SIM card and have internet where ever you go.
