It won't download over 3G, you need to do it manually. Look here:

But how do you account for the fact that the OP has stated that the device will connect to the Kindle Store? Clearly the 3G radio is working. The only thing I can think of which would allow connection to the store, but prevent registration, is blacklisting.
