Access file system?

[tylertech]

I'm just curious... if you could you linux or a mac or something to access the iPhone's internal file system (which I don't think is easily possible), could it be possible you could install third party apps (like those not from the app store) directly to the iPhone?

I believe that's exactly how the early jailbreaks worked, before Installer.

Umm, yeah, you can.
