I too have downloaded it with no problem in Shanghai through the market direct to my phone; I was also impressed at how easy it was to download add-ons in-app, and that it remembered my previous purchases.
I would like to know if there is an easy way to transfer my flashcards from the beta to the China market version. I currently have both running on my phone, so exported to xml file from the beta. However, it is taking an insanely long time to import them back into the China market version, even in unsafe mode. (Over 2,500 cards at around 1 card every 40 seconds). It's not the wait so much, but rather that getting through a call, alert or anything else kills the process. Also, it is very easy to accidentally hit the cancel button.
Is there a faster option, e.g. copying over a database file from the beta into the directory of the Chinese-market version?
