For about approx. 4 hrs, the iDOS app appeard on the App Store! For those not familiar, it's an emulator for all iOS devices (retina support too!) that allows you to run DOS files as well as Windows 3.0. Now that users have gotten the chance to play around, some are reporting that the app allows you to access entire iOS filesystem- without a jailbreak.
Here're the instructions:
Run following commands in iDOS to mount the root directory as a virtual drive"D", change directories to it, and then list everything in the root directory:
Note: You can't remove anything, as you only get read access.
mount d /
You've now listed everything from root without being jailbroken. You can use "copy" command to copy files from wherever you'd like on over to Documents directory (virtual drive C) of iDOS. Run help for info on how to use other commands.
