I'm on a Samsung Nexus, and the content viewer is not able to log in, because of a "no internet connection" error, but I am on WIFI and 3G with the same problems.
I'm having the same issue.
In general, finding this whole DPS thing to be a bit ridiculous anyways. Great prexmise, easy authoring, but getting the result to a device is complete rubbish at this point.
Please uninstall Adobe Air and Adobe content viewer. Install them again.
