I downloaded Pwnage to jailbreak my 2G, and when I attempt to run the Pwnage app, I get this:

There is no application set to open the document “PwnageTool_3.0.dmg.4963802.TPB.torrent”.

My goal is simply to use this old 2g iPhone as a gloried iPod. I haven't used it as an actual phone since I dumped T-Mobile after jailbreaking it originally off AT&T. I have been using it as an iPod, but made the mistake of letting iTunes update and now I'm back to square 1

How can I get this much praised Pwnage to run like an App on MacBook Pro? BTW, I am running Lion OS
