Pandora?

ok i am new to the instinct world.  I am learning about this very interesting phone.  First off i am a Mac user. I think everyone knows instinct and macs are not buddy lol.  I have a few issues that I am trying to resolve.  I have M800 and all i want to do is add Pandora to my phone.  I go to the pandora website and it redirect me to sprint site where i keep getting a download when i try to download the app.  can someone point me in the right directions to get this app?

Unzip the Jad/Jar and upload only the .jar on this site:

This site will sent you a text message with a link to download.....

Warning: you mileage may vary using this technique. I have seen quite a few dowloads that fail
