network.download corona daily sample not working, BUG?

I tried the network async download from the corona sample directory, and it always fall into Network error.
I simply build the sample and put on a galaxy sII, so it should not be build.settings problem, the daily is the 1050 anche the code to reproduce it is the sample code shipped with the sdk.
