How do I use Pandora One on my iPad?
First, you must upgrade to Pandora One on your computer (not your iPad), via our website www.pandora.com. When you upgrade to Pandora One, be sure to use the same Pandora account– the same email address and password– that you use on your iPad. Once you’ve finished upgrading your account from your computer, you can refresh your account state on your iPad. To do that, either restart the Pandora iPad app, or sign out and sign back in to the Pandora app on your iPad. You will now no longer hear or see advertising. Removing advertising is currently the only benefit of Pandora One that applies on the iPad.
