App Store performing well in China despite hindrances

In china Unicorn is selling iphone at a very high
price regarding in America. He is charging 1000$
per iphone. But the sales in iphone is raising day
by day,

The old WiFi restrictions weren't part of the Golden Shield project; they were an attempt to force manufacturers to adopt China's own dead-in-the-water WAPI wireless technology. The restriction was lifted earlier this year, but not soon enough for Apple to start making Unicom-branded handsets with WiFi.

Regarding grey-market phones: these are available for prices comparable to and frequently lower than the official Unicom price; I got mine last year for RMB 4000 or so, and didn't have to sign up for the two-year contract that Unicom pushes. Can't really see how grey-market phones hurt Apple -- they're getting paid either way. And jailbreaking is hardly equivalent to software piracy: most of my iPhone-owning Chinese friends don't use it for anything more than unlocking their phones to run on the carrier of their choice, or -- at most -- installing third-party Chinese input software that replaces Apple's sad, substandard offering.

"Black market phones are a huge problem in China" - Big problem for who exactly? Certainly not Apple who already sold these phones its not like they're stolen. Not for the carriers for sure, since people have to pay for the phone plans regardless.

The only ones losing is the buyers since they have to pay for the re-seller's markup but that is really their choice so I'm sure THEY dont see it as a problem. Try to stick to the facts TUAW.

Where has Apple said they hope to sell 550K iPhones in China by the end of the year? Link?
