A lot of Chinese (non licensed) phones won't allow paid apps to be downloaded from the android market. On the other hand, I DO have a Chinese "no name" phone that downloads everything, including paid apps.
I'm trying to find out where all the information is located how the android market identifies the android device and either allows to download paid apps or denies it
My first guess of course was the build.prob, my friend copied the build.prob from my (paid apps download working) phone to his paid apps non working phone, NO SUCCESS, he still can't download any paid apps with my build.prob.
So, I'm guess there have to be other files(?) that also play a role on how a phone is recognized by the market?
