We now have an android app that you can sideload onto your shield. www.Unblockr.net/Unblockr-DNS.apk
To use Unblockr, you have to change the DNS address of your computer or mobile/multimedia device.
Be sure to make a note of the current server addresses or settings. Keep these numbers for backup purposes in case you need to revert to them.
