Yesterday I put the NCHB 2012 playlist on http://adamsdev.us/BarbershopPitchpipe.html
and told you to just click on it from the browser in your iPhone to install it into the app. I found out today that Safari does not work like the email app does. In the email app you will be given the option to open the file in an associated app. In order to support that from Safari I will have to update my app to support another method so I have an alternative for people to use until I get my fix in place.
The way to make this work is to go to the website and save the file to your location machine (not the iPhone). Insure that it has the .ppl extension. Now email that file to yourself as an attachment. Use your iPhone to read the email and you will be given the option of opening the file with Barbershop Pitchpipe.
Sorry for the inconvenience.
