For those who cant get Orbot : Tor Project to work on your phone > READ THIS
hey guys, theres actually an easier work around to listen to Pandora Radio outside the States, and it doesnt even require you to download Orbot.
Heres how, pop your phone's settings > Wireless & networks > Proxy Setting > set IP to 127.0.0.1 and Port 8118.
Voila! This should work like a charm, enjoy
