To make a long story short, I was trying to get around the sandbox issue encountered while making in app purchases on a jailbroken device. I went into var/private/stash and accidentally deleted 2 files using ifile on my iPad. The 2 files are installed.backup and installed_mount_helper. Where can I find these files to reinstall? I have looked everywhere and nothing. I am on 4.2.1 jailbroken with green poison. I tried rejailbreaking but it's a system file so it doesn't work. My iPad will not go past the boot screen. Thanks for any assistance you can provide.
