Are Passbook Passes Available Outside the Sandbox? With Third Party software, or manually mounting the iPhone to your computer, it's possible to access a limited amount of information. Music, Photos, and App Data. Without breaking the Sandbox, you can never get to the OS itself, and certain data stores.

Are Passbook Passes accessible within this Sandbox? I'd be awesome to see what data is actually contained within them.
I wrote to Macroplant, who make the iExplorer utility that I bought some time ago, and they pointed me to the fact that Passbook Cards are available in the backup data.

When using iExplorer, they're located in the 'Backup Explorer' section, under HomeDomain/Library/Passes/Cards, the Backup Explorer section is apparently a logical mapping of ~/Library/Application Support/MobileSync/Backup/.

That's good enough for me, since data is routinely backed up. I can backup and instantly access my current cards.

Thank you Mike, on the Macroplant Support Team!
