If you live outside the US, and you want to join the following of Pandora Radio, XDA forum member GlobaL_TroTTer has posted a guide on how to do this.
For those of you who don’t know, Pandora Radio is a free personalised radio to stream music on your Android device. It let’s you tap in the name of your favourite artist and Pandora will create a ‘station’ that plays their music or similar.
You will (obviously) need the Pandora Radio apk, which is available free in the Market. (Some of you may require Market Enabler to be able to see the application in the US Market). And you’ll also need Orbot, which is the official port of Tor to Android, which is a tool that allows improvement of privacy and security on the Internet.
The end result is that you will run Pandora through Orbot and be able to listen to Pandora outside of the US!
