Two weeks ago we mentioned how Pandora altered their APIs resulting in all the unofficial Pandora apps for Windows Phone not working. At the time we mentioned that devs should be able to fix the issue with an update to their apps.
Although it's taking a little longer than expected, we're streaming Pandora just fine on Radio Controlled (beta) and we expect the same for the other apps eventually too. The developer of Radio Controlled, Greg Wenograd, let us know about this latest fix:
"This one was a difficult and involved update. I have a feeling this update will be less impacted by Pandora changes. If they change anything it will be sooner rather than later and I should be able to get any kinks worked out....If all goes well I will be submitting the final version tomorrow"
So stand by Pandora users as your fix should be coming soon. You can grab Radio Controlled here in the Marketplace and wait for the new, working update to appear in the next few days.
